Abstract
Disclosed is a voltage non-linear resistor comprising a sintered body composed mainly of zinc oxide, said sintered body including confronting main faces and a face side face connecting the main faces to each other, which has the side face coated with a coating glass layer containing barium oxide. The coating glass layer comprises 40 to 85% by weight of lead oxide, 3 to 25% by weight of boron oxide. 1.5 to 25% by weight of silicon oxide and 0.2 to 15% by weight of barium oxide. The barium oxide acts as a catalyst and exerts a function of completely burning an organic binder at a temperature lower than about 400.degree. C. where the reaction between the organic binder and zinc oxide is not substantially advanced.
