Abstract
Provided is a zinc oxide element which does not contain antimony oxide and has good nonlinear resistance characteristics (V10 kA/V1 mA nonlinearity) by controlling the particle size of zinc oxide particles in a sintered body. The zinc oxide element of the present invention includes a fired body containing zinc oxide, bismuth oxide, and zinc stannate (ZnSO). A method for producing a zinc oxide element of the present invention includes firing a raw material oxide that contains zinc oxide, bismuth oxide, and tin oxide and does not contain antimony oxide, and segregating zinc stannate (ZnSO) at grain boundaries of the fired zinc oxide.
