1. An electromagnetic relay, comprising:
a support member made of an insulating material;
a first fixed terminal supported by the support member, the first fixed terminal including a first fixed contact;
a second fixed terminal supported by the support member at a position apart from the first fixed terminal, the second fixed terminal including a second fixed contact;
a movable contact piece including a first movable contact facing the first fixed contact and a second movable contact facing the second fixed contact; and
a movable member connected to the movable contact piece, the movable member including a first overlapping portion made of an insulating material, the first overlapping portion disposed between the first fixed terminal and the second fixed terminal, the first overlapping portion overlapping with the support member when viewed from a longitudinal direction of the movable contact piece in an open state where the first movable contact is separated from the first fixed contact,
wherein the movable member further includes a second overlapping portion made of an insulating material, the second overlapping portion disposed between the first fixed terminal and the second fixed terminal, the second overlapping portion overlapping with the first fixed contact when viewed from the longitudinal direction of the movable contact piece in the open state, the second overlapping portion protruding from the first fixed contact in a lateral direction of the movable contact piece when viewed from the longitudinal direction of the movable contact piece, the second overlapping portion having a dimension in the lateral direction of the movable contact piece larger than a dimension of the first fixed terminal in the lateral direction of the movable contact piece.
