To reduce variation in electrostatic capacitance between two varistors.SOLUTION: A first internal electrode 31 includes a pair of first connection parts 311 extending along a first direction from a first end surface 11 and connected to a first external electrode 21, and a first counter part 312 provided between the pair of first connection parts 311. A second external electrode 32 includes a pair of second connection parts 321 extending along the first direction from a second end surface 12 and connected to a second external electrode 22, and a second counter part 322 provided between the pair of second connection parts 321. A third internal electrode 33 includes a third counter part 332 disposed along the first direction. The third counter part 332 overlaps with a part of the first counter part 312 and a part of the second counter part 322 in a third direction. A first end 332A of the third counter part 332 in the first direction exists between the pair of first connection parts 311. A second end 332B of the third counter part 332 in the first direction exists between the pair of second connection parts 321.SELECTED DRAWING: Figure 2 【課題】２つのバリスタの静電容量のばらつきを低減すること。【解決手段】第１内部電極３１は、第１端面１１から第１方向に沿って延び、第１外部電極２１に接続される一対の第１接続部３１１と、一対の第１接続部３１１の間に設けられた第１対向部３１２と、を有する。第２内部電極３２は、第２端面１２から第１方向に沿って延び、第２外部電極２２に接続される一対の第２接続部３２１と、一対の第２接続部３２１の間に設けられた第２対向部３２２と、を有する。第３内部電極３３は、第１方向に沿って配置される第３対向部３３２を有する。第３対向部３３２は、第３方向において第１対向部３１２の一部及び第２対向部３２２の一部とそれぞれ重なる。第１方向における第３対向部３３２の第１端３３２Ａは一対の第１接続部３１１の間に配置され、第１方向における第３対向部３３２の第２端３３２Ｂは一対の第２接続部３２１の間に配置されている。【選択図】図２
