ABSTRACT:
There is provided a chip type varistor having a small electrostatic capacity, high voltage non-linearity, and high voltage suppressing capability and surge resistance. The chip type varistor is a layered body formed by a plurality of ceramic layers mainly composed of SiC containing at least two elements, in the form of oxides, selected from among Si, Bi, Pb, B and Zn, an inner electrode layer interposed between the ceramic layers of the layered body, and an outer electrode formed on the surface of the layered body and electrically connected to the inner electrode layer.
