Abstract
A voltage non-linear type sintered resistor is disclosed, which is produced by reacting, under heating, a mixture consisting essentially of zinc oxide as a main component, and an additive exhibiting voltage non-linearity and silicon oxide as auxiliary components. The silicon oxide is contained in an amount of 0.3 to 4.0 mol % with respect to the sintered resistor when calculated as SiO.sub.2, and the average particle diameter of crystalline grains of the zinc oxide constituting the sintered body is not more than 6 .mu.m.
