ABSTRACT:
A non-linear resistor having a high impulse withstanding ability is obtained by directly applying a crystallized glass to the side surface of a sintered body of a ZnO element, and then bake-attaching the crystallized glass to the side surface of the ZnO element by heat treatment. Since the impulse withstanding ability is improved by applying the crystallized glass as the side surface high-resistivity layer of the voltage non-linear resistor, the performance and reliability of an arrester including the resistor is improved.
