摘要:
In a laminate type ceramic electronic component, when an external electrode for a laminated ceramic capacitor is formed directly by plating onto a surface of a component main body, the film that is directly plated may have a low fixing strength with respect to the component main body. As the external electrode, a first plating layer composed of a Ni—P plating film with a P content rate of about 9 weight % or more 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 P is formed on the first plating layer. Preferably, the first plating layer is formed by electroless plating, whereas the second plating layer is formed by electrolytic plating.
