Abstract
Provided is a technique to secure compositional or microstructural uniformity of a ceramic sintered body while increasing the area of the ceramic sintered boy, thus improving basic performance including non-linearity, maximum withstand energy and aging characteristics. A plurality of small varistor piecesand insulating resin are kneaded and extruded for shaping, whereby a sheet-form varistor layercan be formed where a plurality of small varistor piecesare spaced from one another and are aligned on the same plane, and the adjacent small varistor piecesare bonded via insulating resin.
