Abstract:
1. A chip varistor comprising: a varistor section comprised of a sintered body containing ZnO as a major component, configured to exhibit the nonlinear voltage-current characteristics, and having a pair of principal surfaces opposed to each other; and a plurality of terminal electrodes connected to the varistor section, wherein each of said terminal electrodes has a first electrode portion connected to either of the principal surfaces and a second electrode portion connected to the first electrode portion, wherein the varistor section includes a first region where at least one element selected from the group consisting of alkali metals, Ag, and Cu exists, and a second region extending between the pair of principal surfaces and containing no element selected from the group consisting of alkali metals, Ag, and Cu, and wherein the first electrode portions are connected to the second region.
