Abstract
An external electrode included in a laminated ceramic electronic component is formed on a ceramic body by baking a conductive paste including a glass component. The ceramic body with the conductive paste applied thereto is subjected to heat treatment under the conditions where the top temperature is 800° C. or higher, and the electromotive force at the top temperature is 600 to 900 mV. In this heat treatment, the glass component in the conductive paste penetrates into grain boundaries between ceramic grains of the ceramic body, and a crystalline substance containing elements constituting the glass component is generated which has dissolving resistance against plating solutions.
