Zusammenfassung: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.
