ELECTRONIC PARTS AND MANUFACTURING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide electronic parts with a high reliability which prevent plating liquid from passing through an external electrode and from penetrating into a ceramic element and prevent humidity in an outside environment from inwardly penetrating, and which don't produce any solder sticking failure and any solder splitting failure resulting from the fact that a glass component deposits on a front surface of the external electrode, and to provide a method of manufacturing the electronic parts. SOLUTION: The electronic parts are provided with Cu baking electrode layers 6a, 6b which make Cu a principal component; Cu plating layers 7a, 7b formed on the Cu baking electrode layers 6a, 6b, in which a recrystallization treatment is performed; and upper layer side plating layers 9a, 9b formed on the Cu plating layers 7a, 7b. After forming the Cu plating layers 7a, 7b, the Cu plating layers 7a, 7b are recrystallized by performing a heat treatment at a temperature more than a temperature at which the Cu plating layers 7a, 7b are recrystallized, and at a temperature at which any glass contained in conductive paste is not softened.
