A sintered body which can be formed into a resistor having a non-linear resistance includes zinc oxide is the principal composition and bismuth, cobalt, antimony, manganese and nickel respectively converted to expressed Bi2O3, Co2O3, Sb2O3, MnO and NiO as auxiliary compositions. The compositions contains 0.05 to 10 mol % of Bi2O3, 0.05 to 10 mol % of Co2O3, 0.05 to 10 mol % of Sb2O3, 0.05 to 10 mol % of MnO and 0.05 to 10 mol % of NiO; the content ratio of the Bi2O3 to the NiO is in a mole ratio of 0.5 or more but 1.5 or less, and the content ratio of the MnO to the Sb2O3 is in a mole ratio of 1.0 or less. Preferably, the composition contains at least one of 0.5 to 500 ppm of aluminum, converted to Al3+, and 10 to 1000 ppm of at least one or the other of boron and silver, converted respectively to B3+, and Ag+. The composition may also contain 0.01 to 1000 ppm of at least one of sodium, potassium, chlorine and calcium, converted respectively to Na+, K+, Cl− and Ca2+.
