Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic relay capable of reducing electromagnetic repulsive force which causes the separation between a fixed terminal block and a movable contact piece, and also capable of flowing a higher current, without the use of a large electromagnet device.SOLUTION: A movable contact piece 20 is provided with a square-shaped through-hole 20c having a width shorter than a diameter of a fixed terminal block 10 so that the movable contact piece 20 and the fixed terminal block 10 are brought into contact with each other at two positions, thereby reducing electromagnetic repulsive force generated between the movable contact piece 20 and the fixed terminal block 10. Consequently, a contact load can be reduced to enable the use of a small electromagnet device, thereby making it possible to reduce the size of an electromagnetic relay. Further, a higher current can be flown between the fixed terminal block 10 and the movable contact piece 20.
