Abstract: 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.

Abstract: A ceramic electronic component includes a ceramic element including opposed side surfaces, an inner electrode, and an external terminal electrode. The external terminal electrode includes a first conductive layer and a second conductive layer. The first conductive layer is formed by plating so as to be electrically coupled to an exposed section of the internal electrode exposed to the side surfaces. The second conductive layer is arranged so as to cover the first conductive layer and includes conductive resin. The value of T2/T1 is in the range of about 3.4 to about 11.3, where T1 indicates the thickness of the first conductive layer and T2 indicates the thickness of the second conductive layer.
