Abstract: A laminate includes insulating layers laminated to each other. Capacitor conductors are embedded in the laminate and have exposed portions exposed between the insulating layers at respective surfaces of the laminate. The capacitor conductors define a capacitor. External electrodes are provided by plating on the respective surfaces of the laminate so as to directly cover the respective exposed portions. When the laminate is viewed in plan in a y axis direction, the length of each of the exposed portions is approximately 35% to approximately 45% of the length of an outer periphery of the insulating layer.

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.
