ABSTRACT:
A voltage non-linearity type resistor and a process for the preparation of a voltage non-linearity type resistor wherein pre-sintering is effected at a temperature of no lower than 700.degree. C. with a basic composition including X mole % of ZnO and (100-X) mole % of Fe.sub.2 O.sub.3 (wherein 40.ltoreq.X.ltoreq.60), and sintering is then effected with the resulting pre-sintered body to which at least one of V.sub.2 O.sub.5, Bi.sub.2 O.sub.3, MgO, Al.sub.2 O.sub.3, MoO.sub.3, Sb.sub.2 O.sub.3, SiO.sub.2, NiO, SrO.sub.2 and PbO is further added in a proportion of 0.01-40% by weight.
