An electromagnetic relay device includes a mover, a plunger, and a solenoid unit that causes the plunger to reciprocate. The mover includes a movable contact movable to abut onto or separate from a stationary contact. The plunger causes the mover to reciprocate to accordingly cause the movable contact to abut onto or separate from the stationary contact. A heat-resistant member is interposed between the insulator and the mover. The plunger enables indirect abutment onto the mover through the insulator and the heat-resistant member. A heat-resistant temperature of the heat-resistant member is set to be higher than that of the insulator.

An electromagnetic relay includes a first fixed terminal including a first fixed contact, a second fixed terminal including a second fixed contact, a movable contact piece, a case, a drive device, and a first magnet. The movable contact piece includes a first movable contact and a second movable contact. The case includes an accommodation space and a side wall covering the accommodation space in a first direction. The first magnet extends an arc generated between the first fixed contact and the first movable contact in a second direction opposite to the first direction. The first fixed terminal includes a first end. The first end of the first fixed terminal includes a tapered portion inclined in the second direction from the first fixed contact toward the first magnet and that at least partially overlaps with the first magnet when viewed from a moving direction of the movable contact piece.

A base of a relay has a leg extending in a contact/separation direction between contacts, and the leg is configured to come into contact with a yoke when the base is incorporated into a case. The leg is spaced away from an upper part of an armature by a distance. This distance is determined so that an upper surface of the armature does not come into contact with the leg in a normal operation of the armature, but the upper surface of the armature comes into contact with a lower surface of the leg when the armature jumps up beyond a movable range thereof due to, for example, a strong impact applied to a vehicle on which the relay is mounted.
