<p>The varistor element 2 of the present invention has a pair of electrodes 3 and 4 accommodated on the outer surfaces of a varistor element 2. The pair of electrodes 3 and 4 are comprised of a pair of ohmic contact electrodes 5 and 6, oppositely arranged on top/bottom surfaces of the varistor element, and a pair of non-ohmic contact electrodes 7 and 8, covering both ends of the varistor element 2 so as to form terminal electrodes. The non-ohmic contact electrodes 7 and 8 are, respectively, connected to the pair of ohmic contact electrodes 5 and 6. With this structure, an electric current is not concentrated at the ends of the ohmic contact electrodes. As a result, the endurance against surge currents increased and the reliability and durability of the product is improved.</p> |
