Claims4
A ceramic electronic component comprising:
- an electronic component body including a superficial base ceramic layer;
- a surface electrode on a surface of the electronic component body, the surface electrode including:
- a first sintered layer on the superficial base ceramic layer,
- a second sintered layer on the first sintered layer, and
- a plating layer on the second sintered layer and located in a central section of the surface electrode,
- the first sintered layer and the second sintered layer defining a peripheral section of the surface electrode and having an opening therein that extends through the first sintered layer and the second sintered layer;
- and
- a covering ceramic layer covering the peripheral section of the surface electrode and the opening therein and not covering the plating layer, wherein
- the opening in the peripheral section is filled with a ceramic component contained in the superficial base ceramic layer or a glass component contained in the superficial base ceramic layer.
