Abstract
A voltage non-linear resistor having a voltage non-linear resistance element consisting mainly of zinc oxides and a high resistance layer including a zinc silicate phase consisting mainly of Zn.sub.2 SiO.sub.4 and a spinel phase consisting mainly of Zn.sub.7 Sb.sub.2 O.sub.12 has a continuous zinc silicate phase in which zinc silicate particles are arranged continuously. Therefore, in the voltage non-linear resistor according to the invention, a flashover can be preferably prevented, and thus a stable electric characteristics especially lightning discharge current withstanding capability can be obtained.
