摘要
A voltage nonlinear resistor according to the present invention is made of a sintered body that mainly comprises zinc oxide grains, spinel grains containing zinc and antimony as main ingredients, and a bismuth oxide phase, in which the bismuth oxide phase contains at least one of alkali metals selected from the group consisting of potassium and sodium at a ratio in the range of 0.036 at% or higher and 0.176 at% or lower. The voltage nonlinear resistor has good voltage nonlinearity and loading service life characteristics, and is therefore suitably used for a lightning arrester.
