Abstract of the Disclosure A composite sintered oxide resistor comprising crystal grains of zinc oxide and crystal grains of a zinc oxide compound of other metal or semi-metal element than zinc, and a grain boundary layer having an electric resistance equal to or lower than that of the crystal grains of zinc oxide between the individual crystal grains of which has a very large withstanding capacity against switch surge, a small non-linear coefficient of voltage in the voltage- current characteristics, a positive, smaller resistance- temperature coefficient, and a small percent change in resistivity after heat treatment at 500°C in the atmosphere.
