PROBLEM TO BE SOLVED: To provide an electromagnetic relay in which a movable iron piece is brought into stable state on early stage and which has stable operation characteristics.SOLUTION: An electromagnetic relay comprises a gate-shaped iron core 30, a movable iron piece 40 and a card 50. The card 50 is pressed with the movable iron piece 40 which is rotated based on magnetization/demagnetization of an electromagnet unit 20, thereby driving a contact mechanism unit 60. In particular, a shallow groove 33 that is magnetic flux density reduction means, is provided on at least one counter surface between counter surfaces of one leg 32 of the gate-shaped iron core 30 and a rotary shaft 43 of the movable iron piece 40. |
