性において十分な特性は得られていない。[Technical background of the invention and its problems] Various voltage-current non-linear resistors have been studied in the past, and one of them uses a sintered body containing ZnO as a main component. In C2, which uses a sintered body containing ZnO as a main component, attempts have been made to add various subcomponents to obtain desired characteristics. The characteristics required of such a voltage-current non-linear resistor include voltage-current non-linear characteristics, life-span characteristics, etc., but it is difficult to obtain one that has excellent characteristics in all of them. For example, Japanese Patent Application Publication No. 4

There are voltage-current non-linear resistors in which B, Nip, and MnO are added as subcomponents, but in this case as well, sufficient voltage-current non-linear characteristics are not obtained.

寿命特性に優れたものが要求される。Attempts have been made to obtain a voltage-current nonlinear resistor in which the limiting voltage does not decrease in direct current flow by adding and sintering ZnO containing ZnO as a main component and containing boron oxide. However, even in such a voltage-current non-linear resistor, excellent voltage-current non-linear characteristics and life characteristics of ≦2 have not been obtained. Especially when the purpose is to absorb large surges such as lightning arresters,
A product with excellent life characteristics is required.

This is because non-linear characteristics and life characteristics deteriorate. The reason why 7'CAJ8+ is set to 0.001 to 0.05 mo1% is because if it deviates from this range, the nonlinear characteristics, life characteristics (%), and nonlinear characteristics will deteriorate significantly.
