Abstract:
In a laminate type ceramic electronic component, when an external electrode is formed directly by plating onto a surface of a component main body, the plating film that is to serve as the external electrode may have a low fixing strength with respect to the component main body. In order to prevent this problem, an external electrode includes a first plating layer composed of a Ni—B plating film and is first formed such that a plating deposition deposited with the exposed ends of respective internal electrodes as starting points is grown on at least an end surface of a component main body. Then, a second plating layer composed of a Ni plating film containing substantially no B is formed on the first plating layer. Preferably, the B content of the Ni—B plating film constituting the first plating layer is about 0.1 wt % to about 6 wt %.
