Abstract
An ESD protective device includes an element assembly with a hollow portion that includes inner surfaces including a first inner surface, a second inner surface, and a third inner surface inclined to a Z direction in a cross section including the Z direction. Accordingly, a surface area of the inner surfaces of the hollow portion is increased, the heat load on an auxiliary discharge electrode is reduced, and the deterioration of the auxiliary discharge electrode is significantly reduced or prevented.
