Abstract
A varistor has a ceramic composition to exhibit nonlinear voltage-current characteristics, and at least two electrodes arranged to sandwich at least a portion of the ceramic composition. The ceramic composition contains a mixture phase in which a first phase containing zinc oxide as a major component, and a second phase comprised of an oxide of Ca and Si are mixed.
