Abstract
In a method for manufacturing a laminated ceramic electronic component, after a plating layer for an external terminal electrode is formed by applying copper plating to an end surface of a component main body at which respective ends of a plurality of internal electrodes primarily including nickel are exposed, when a heat treatment at a temperature of about 800° C. or more is applied in order to improve adhesion strength and resistance to moisture of the external terminal electrode, voids may occur in the plating layer. The step of applying a heat treatment at a temperature of about 800° C. or more to a component main body with plating layers formed thereon includes not only a step of maintaining a top temperature of about 1000° C. or more but also a step of maintaining a temperature of about 600° C. to 900° C. at least once before the step of maintaining the top temperature.
