Abstract

A ceramic electronic component includes an electronic component body, an inner electrode, and an outer electrode. The outer electrode includes a fired electrode layer and first and second plated layers. The fired electrode layer is disposed on the electronic component body. The first plated layer is disposed on the fired electrode layer. The thickness of the first plated layer is about 3 μm to about 8 μm, for example. The first plated layer contains nickel. The second plated layer is disposed on the first plated layer. The thickness of the second plated layer is about 0.025 μm to about 1 μm, for example. The second plated layer contains lead.

Claims (17)

1. A ceramic electronic component comprising:

an electronic component body including first and second principal surfaces extending along a longitudinal direction and a widthwise direction, first and second side surfaces extending along the longitudinal direction and a thickness direction, and first and second end surfaces extending along the widthwise direction and the thickness direction;

an inner electrode disposed within the electronic component body; and

an outer electrode that is disposed on the electronic component body and that is electrically connected to the inner electrode; wherein

the outer electrode includes:

a fired electrode layer disposed on the electronic component body;

a first plated layer that is disposed on the fired electrode layer and that is a Ni-plated layer having a thickness of about 3 μm to about 8 μm; and

a second plated layer that is disposed on the first plated layer and that is a Pd-plated layer having a thickness of about 0.025 μm to about 1 μm.

2. The ceramic electronic component according to claim 1 , wherein the fired electrode layer contains glass.
