1. An electromagnetic relay comprising:
a base;
a first fixed terminal including a first fixed contact, the first fixed terminal being supported by the base;
a second fixed terminal including a second fixed contact, the second fixed terminal being supported by the base at a position separated from the first fixed terminal;
a movable contact piece including a pair of movable contacts, the pair of movable contacts configured to contact the first fixed contact and the second fixed contact;
a movable member to which the movable contact piece is fixed, the movable member being movable in a contact direction in which the first fixed contact and the second fixed contact come into contact with the pair of movable contacts and in a separation direction in which the first fixed contact and the second fixed contact are separated from the pair of movable contacts; and
a return spring disposed between the base and the movable member, the return spring configured to urge the movable member in the separation direction, wherein
the base includes a guide portion to guide movement of the movable member,
the movable member includes a sliding portion slidable with respect to the guide portion,
the return spring is disposed inside the guide portion,
the guide portion is disposed in the contact direction with respect to the first fixed contact and the second fixed contact, and
the movable contact piece is fixed to be immovable relative to the movable member in the contact and separation directions.
