Abstract

This disclosure provides an electronic component that can suppress a decrease in the resonant frequency. The electronic component includes a multilayer body having plural insulating layers stacked in a staking direction. Outer electrodes are provided on facing lateral sides of the multilayer body and extend in the stacking direction. Coil conductors are stacked together with the insulating layers to form a coil. The thickness in the stacking direction of at least one of the coil conductors that is directly connected to one of the outer electrodes is smaller than that of the coil conductors that are not directly connected to any of the outer electrodes.

Claims (21)

1. An electronic component comprising:

a multilayer body having plural insulating layers stacked in a stacking direction;

two outer electrodes on respective facing lateral sides of the multilayer body and extending in the stacking direction; and

plural coil conductors stacked together with the insulating layers to form a coil,

wherein at least one of the coil conductors is directly connected to one of the outer electrodes and has a thickness in the stacking direction that is smaller than a thickness in the stacking direction of portion of a coil conductor of the plural coil conductors that is not directly connected to one of the outer electrodes overlapping in the stacking direction with the directly connected coil conductor.

2. The electronic component according to claim 1 , wherein the thickness in the stacking direction of at least one of the coil conductors is from ⅓ to ½ the thickness of the coil conductor that is not directly connected to one of the outer electrodes.

3. The electronic component according to claim 1 , wherein another one of the plural coil conductors is directly connected to another one of the outer electrodes and has a thickness in the stacking direction that is smaller than the thickness of the coil conductor that is not directly connected to one of the outer electrodes.

4. The electronic component according to claim 1 , wherein the entire at least one coil conductor directly connected to one of the outer electrodes has the thickness smaller than a thickness in the stacking direction of one of the plural coil conductors that is not directly connected to one of the outer electrodes.

5. The electronic component according to claim 1 , wherein the coil is a double spiral coil.

6. An electronic component comprising:

a multilayer body having plural insulating layers stacked in a stacking direction;

first and second outer electrodes on respective facing lateral sides of the multilayer body and extending in the stacking direction; and

plural coil conductors stacked together with the insulating layers to form a coil,

wherein

the plural coil conductors form a substantially rectangular orbit in the stacking direction,

a thickness in the stacking direction of a portion of one of the coil conductors that is directly connected to the first outer electrode, the portion being most adjacent to the second outer electrode and forming a side of the substantially rectangular orbit, is smaller than a thickness in the stacking direction of one of the plural coil conductors that is not directly connected to the first or second outer electrode.

7. The electronic component according to claim 6 , wherein the thickness in the stacking direction of at least one of the coil conductors is from ⅓ to ½ the thickness of the coil conductor that is not directly connected to the first or second outer electrode.

8. The electronic component according to claim 6 , wherein

another one of the plural coil conductors is directly connected to another one of the outer electrodes and has a thickness in the stacking direction that is smaller than the thickness of the coil conductor that is not directly connected to the first or second outer electrode.

9. The electronic component according to claim 6 , wherein only the portion being most adjacent to the second outer electrode has the thickness smaller than a thickness in the stacking direction of the plural coil conductor that is not directly connected to the first or second outer electrode.

10. The electronic component according to claim 6 , wherein the coil is a double spiral coil.
