Abstract
An electronic component that includes: a ceramic body; and an external electrode on a surface of the ceramic body, wherein the external electrode includes: a base layer in contact with the surface of the ceramic body, the base layer including a granulate of a metal material and a continuous phase of a titanium-containing oxide present around the granulate of the metal material; and a plating layer on the base layer.
Claims9
An electronic component comprising:
- a ceramic body;
- and
- an external electrode on a surface of the ceramic body, the external electrode including:
- a base layer in contact with the surface of the ceramic body, the base layer including a granulate of a metal material and a continuous phase of a titanium-containing oxide present around the granulate of the metal material;
- and
- a plating layer on the base layer,
- wherein a density of the metal material in a first portion of the base layer closer to the plating layer is higher than a density of the metal material in a second portion of the base layer closer to the surface of the ceramic body, and
- wherein the base layer has a thickness of 1.5 μm or less.
