Abstract

An electronic component includes: a first internal electrode provided in an element body; a second internal electrode provided in the element body; a third internal electrode provided in the element body and drawn out to a first side surface; and a fourth internal electrode provided in the element body and drawn out to a second side surface. The third internal electrode and the fourth internal electrode are electrically connected to each other through an external connection conductor formed on at least the first side surface and the second side surface. In a first direction, the first internal electrode faces the third internal electrode without facing the second internal electrode and the fourth internal electrode. In the first direction, the second internal electrode faces the fourth internal electrode without facing the first internal electrode and the third internal electrode.

Claims (39)

1. An electronic component, comprising:

an element body having a first main surface and a second main surface facing each other in a first direction, a first end surface and a second end surface facing each other in a second direction perpendicular to the first direction, and a first side surface and a second side surface facing each other in a third direction perpendicular to the first and second directions;

a first terminal electrode formed on the first end surface;

a second terminal electrode formed on the second end surface;

a first internal electrode provided in the element body and connected to the first terminal electrode at the first end surface;

a second internal electrode provided in the element body and connected to the second terminal electrode at the second end surface;

a third internal electrode provided in the element body and drawn out to the first side surface; and

a fourth internal electrode provided in the element body and drawn out to the second side surface,

wherein the third internal electrode and the fourth internal electrode are electrically connected to each other through an external connection conductor formed on at least the first side surface and the second side surface,

in the first direction, the first internal electrode faces the third internal electrode without facing the second internal electrode and the fourth internal electrode, and

in the first direction, the second internal electrode faces the fourth internal electrode without facing the first internal electrode and the third internal electrode.

2. The electronic component according to claim 1 ,

wherein the first internal electrode and the second internal electrode are arranged in outermost layers of stacked internal electrodes.

3. The electronic component according to claim 1 ,

wherein the element body has a gap portion in which no internal electrode is formed when viewed from the first direction.

4. The electronic component according to claim 3 ,

wherein a width of the gap portion in the second direction is equal to or greater than an interlayer thickness of the element body.

5. The electronic component according to claim 1 ,

wherein the external connection conductor extends to the first side surface, the second side surface, and the first main surface, and

on the second main surface, one end and the other end of the external connection conductor are spaced apart from each other in the third direction.

6. The electronic component according to claim 1 ,

wherein the external connection conductor is arranged so as not to overlap the first internal electrode and the second internal electrode when viewed from the first direction.

7. The electronic component according to claim 1 ,

wherein the first terminal electrode and the second terminal electrode include a conductive resin layer.

8. An electronic component, comprising:

an element body having a first main surface and a second main surface facing each other in a first direction, a first end surface and a second end surface facing each other in a second direction perpendicular to the first direction, and a first side surface and a second side surface facing in a third direction perpendicular to the first and second directions;

a first terminal electrode formed on the first end surface;

a second terminal electrode formed on the second end surface;

a first internal electrode provided in the element body and connected to the first terminal electrode at the first end surface;

a second internal electrode provided in the element body and connected to the second terminal electrode at the second end surface;

a third internal electrode provided in the element body and drawn out to the first side surface;

a fourth internal electrode provided in the element body and drawn out to the second side surface;

a fifth internal electrode provided in the element body, arranged between the first internal electrode and the second internal electrode in the second direction, and drawn out to the first side surface; and

a sixth internal electrode provided in the element body, arranged between the third internal electrode and the fourth internal electrode in the second direction, and drawn out to the second side surface,

wherein the third internal electrode and the sixth internal electrode are electrically connected to each other through a first external connection conductor formed on at least the first side surface and the second side surface,

the fourth internal electrode and the fifth internal electrode are electrically connected to each other through a second external connection conductor formed on at least the first side surface and the second side surface,

in the first direction, the first internal electrode faces the third internal electrode without facing the second internal electrode, the fourth internal electrode, the fifth internal electrode, and the sixth internal electrode,

in the first direction, the second internal electrode faces the fourth internal electrode without facing the first internal electrode, the third internal electrode, the fifth internal electrode, and the sixth internal electrode, and

in the first direction, the fifth internal electrode faces the sixth internal electrode without facing the first internal electrode, the second internal electrode, the third internal electrode, and the fourth internal electrode.
