ABSTRACT:
A voltage non-linear resistor comprises a sintered body of a ceramic composition comprising zinc oxide at a ratio of 99.88 to 84.88 mol % as ZnO; a praseodymium oxide component at a ratio of 0.01 to 0.035 mol % as Pr.sub.2 O.sub.3 and a lanthanum oxide component at a ratio of 0.01 to 0.035 mol % as La.sub.2 O.sub.3 and a cobalt oxide component at a ratio of 0.1 to 15 mol % as CoO and a specific additional component selected from chromium oxide, boron oxide, silicon oxide, titanium oxide, tin oxide, zirconium oxide, niobium oxide, tantalum oxide, tungsten oxide and germanium oxide at a ratio of 0.0001 to 0.05 mol %.
