Abstract
There is provided a varistor having high surge resisting capability in spite of its small size and a method of manufacturing the same. The varistor is mainly composed of zinc oxide and contains a composite oxide expressed by the chemical formula Zn SnO . It is manufactured using a method wherein zinc oxide and tin oxide are mixed; the mixture is subjected to a thermal process thereafter to obtain a composite oxide expressed by the chemical formula Zn SnO ; and the composite oxide is combined with the zinc oxide which is the main component and a thermal process is performed to obtain a raw material for the varistor.
