To delay an increase in the temperature of a stationary terminal during energization in an electromagnetic relay.SOLUTION: An electromagnetic relay comprises: a stationary terminal; a movable contact piece; a support member; and an endothermic member. The stationary terminal includes a stationary contact and an external connection part that is connected to an external apparatus. The movable contact piece includes a movable contact that can be in contact with the stationary contact. The support member supports the stationary terminal. The endothermic member is a different body from the support member, in contact with the stationary terminal in a state in which the stationary contact and the movable contact are in contact, and has a heat capacity larger than the heat capacity in the stationary terminal from the stationary contact to the external connection part.SELECTED DRAWING: Figure 1 【課題】電磁継電器において、通電時における固定端子の温度上昇を遅らせる。【解決手段】電磁継電器は、固定端子と、可動接触片と、支持部材と、吸熱部材と、を備える。固定端子は、固定接点と、外部機器に接続される外部接続部とを含む。可動接触片は、固定接点に接触可能な可動接点を含む。支持部材は、固定端子を支持する。吸熱部材は、支持部材と別体であり、固定接点と可動接点とが接触した状態において固定端子に接触し、固定接点から外部接続部までの間の固定端子における熱容量よりも熱容量が大きく【選択図】図１
