Abstract

An electronic component includes an element body having a functional layer and an internal electrode layer, and an external electrode formed on a surface of the element body and connected to the internal electrode layer electrically. The chlorine concentration of the element body of the electronic component is 10 ppm or less.

Claims (14)

1. An electronic component, comprising:

an element body including a functional layer and an internal electrode layer; and

an external electrode formed on a surface of the element body and connected to the internal electrode layer electrically, wherein

the chlorine concentration of the element body is greater than 0 ppm and equal to or less than 10 ppm, and

the element body is obtained by using an internal electrode layer paste containing a barium titanate inhibitor with a chlorine concentration of 50 ppm or less.

2. The electronic component according to claim 1 , wherein

the element body includes an inner-layer dielectric layers-region where the functional layer and the internal electrode layer are laminated alternately, and an outer-layer-region located on at least one end surface of the inner-layer dielectric layers-region in a direction in which the functional layer and the internal electrode layer are laminated; and

the chlorine concentration of the functional layer in the inner-layer dielectric layers-region is greater than 0 ppm and equal to or less than 10 ppm.

3. The electronic component according to claim 2 , wherein the internal electrode layer includes a conductive material containing at least one element selected from the group consisting of nickel and copper.

4. The electronic component according to claim 2 , wherein the average particle diameter of the inhibitor is 100 nm or smaller.

5. The electronic component according to claim 2 , wherein a composition of the inhibitor is the same as a composition of a main component of the functional layer.

6. The electronic component according to claim 1 , wherein the internal electrode layer includes a conductive material containing at least one element selected from the group consisting of nickel and copper.

7. The electronic component according to claim 1 , wherein the average particle diameter of the inhibitor is 100 nm or smaller.

8. The electronic component according to claim 1 , wherein a composition of the inhibitor is the same as a composition of a main component of the functional layer.
