An electromagnetic relay deicing system includes an electromagnetic relay that includes a common terminal, a normally open terminal, and a normally closed terminal and that supplies electric power from an electric power supplier to an electrical apparatus when the common terminal and the normally open terminal are connected, and a control circuit that controls an on-state and an off-state of the electromagnetic relay. During the on-state of the electromagnetic relay, the common terminal and the normally open terminal are connected by a movable piece. During the off-state of the electromagnetic relay, the common terminal and the normally closed terminal are connected by the movable piece. The control circuit deices the electromagnetic relay by causing, during the off-state of the electromagnetic relay, electric conduction between the common terminal and the normally closed terminal connected by the movable piece so that ice on a surface of the normally open terminal melts.
