Abstract: A varistor includes an effective layer having first and second surfaces opposite to each other, a first ineffective layer stacked on the first surface of the effective layer, a second ineffective layer stacked on the second surface of the effective layer, and an external electrode. The effective layer includes a ceramic layer having a polycrystalline structure including crystal particles exhibiting voltage nonlinear characteristics, and internal electrodes stacked alternately on the ceramic layer. The thickness of the second ineffective layer is equal to or more than 1.1 times a thickness of the first ineffective layer and equal to or smaller than 6 times the thickness of the first ineffective layer. This varistor has a small size and excellent surge resistance.

Abstract: Provided is a varistor assembly capable of achieving good surge breakdown voltage while suppressing capacitance. The varistor assembly is obtained by connecting a plurality of varistor elements in parallel. Each varistor element includes: a sintered body obtained by sintering a laminate in which varistor layers and internal electrodes are alternately laminated; and a pair of external electrodes provided in a state where the internal electrodes are alternately connected on at least both end faces of this sintered body. Varistor element includes at least a plurality of first group varistor elements in which a value obtained by dividing a surface area of the sintered body by a volume of the sintered body is 1.9 mm−1 or more.
