<p>PROBLEM TO BE SOLVED: To provide a multilayer chip varistor with improved heat cycle resistivity, improved solder wettability, and a sufficient surge resisting amount. SOLUTION: In a multilayer chip varistor according to present invention, an external electrode has a three layer structure including first layers 2a, 2b, second layers 3a, 3b formed outside of the first layers 2a, 2b, and third layers 4a, 4b formed outside of the second layers 3a, 3b. Glass content in the first layers 2a, 2b is made to be 2-4%, glass content in the second layers 3a, 3b, 4-10%, and glass content in the third layers 4a, 4b, 0-4%.</p> |
