1. An electromagnetic relay device comprising:
a mover including a movable contact movable to abut onto and separate from a stationary contact;
a plunger configured to cause the mover to reciprocate to accordingly cause the movable contact to abut onto or separate from the stationary contact;
a solenoid unit configured to cause the plunger to reciprocate;
an insulator having a heat-resistant temperature and arranged between the mover and the plunger; and
a heat-resistant member having a heat-resistant temperature and interposed between the insulator and the mover, the plunger enabling indirect abutment onto the mover through the insulator and the heat-resistant member, the heat-resistant temperature of the heat-resistant member being set to be higher than the heat-resistant temperature of the insulator.
