Abstract: A varistor is provided with a varistor element, and an external electrode disposed on the varistor element. The varistor element contains ZnO as a principal ingredient and contains a rare-earth element and Ca. The external electrode is formed by baking on an outer surface of the varistor element and contains Pt. When the external electrode is formed by baking on the varistor element, a compound of the rare-earth element and Pt and a compound of Ca and Pt are formed near an interface between the varistor element and the external electrode, and exist there. The existence of these compounds enhances the bonding strength between the varistor element and the external electrode.
