Patent ID: 7994893

Claim:
A multilayer chip varistor comprising: a varistor element body that includes: a varistor portion having a nonlinear resistor layer composed of a ceramic composition to exhibit nonlinear voltage-current characteristics, and at least two internal electrodes arranged to sandwich at least a portion of the nonlinear resistor layer; and a pair of outer layer portions arranged to sandwich the varistor portion, the varistor portion and the pair of outer layer portions being laminated; and a plurality of external electrodes arranged on opposed end faces of the varistor element body, wherein 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, and in a cut surface of the ceramic composition, an area ratio of the second phase to the cut surface is in the range of not less than 0.04 nor more than 0.38.
