Zusammenfassung:The problem addressed by the present disclosure is to provide a multilayer varistor which can improve reliability by reducing peeling, cracking, and the like even in harsh environments. A multilayer varistor (1) is provided with a sintered body (11), a first external electrode (13A), a second external electrode (13B), a first internal electrode (12A), a second internal electrode (12B), and a high-resistivity part (16). The first internal electrode (12A) is provided inside the sintered body (11) and is electrically connected to the first external electrode (13A). The second internal electrode (12B) is provided inside the sintered body (11) and is electrically connected to the second external electrode (13B). The high-resistivity section (16) comprises: a surface high-resistivity section (14) provided so as to cover the surface of the sintered body (11); and an internal high-resistivity part (15) extending from the surface high-resistivity part (14) to the inside of the sintered body (11). 本公开解决的问题是提供多层压敏电阻器,所述
