<p>PROBLEM TO BE SOLVED: To obtain a current-voltage nonlinear resistor having an excellent resistance characteristic, life characteristic, and surge energy withstand characteristic. SOLUTION: In this current-voltage nonlinear resistor 1 composed of a sintered compact 2 containing ZnO as the main component, the sintered compact 2 contains Bi, Co, Mn, Sb, Ni, and Al as accessory components at rates of 0.3-2 mol%, 0.3-1.5 mol%, 0.4-6 mol%, 0.8-7 mol%, 0.5-5 mol%, and 0.001-0.2 mol% in terms of Bi2O3, Co2O3, MnO, Sb2O3, NiO, and Al3+, respectively. In the Bi2O3 crystal phase of the sintered compact 2, anα-Bi2O3 phase occupies the >=80% of the whole Bi2O3 phase.</p> |
