Claim Text:
1. An electromagnetic relay, comprising: an iron core having legs at both ends and a coil wound therearound to form an electromagnet; a movable iron piece that pivotally supports a pivoting shaft along one leg of the iron core and causes a tip of a pivoting arm extended from a side edge of the pivoting shaft toward the other leg of the iron core to face the other leg of the iron core in a contactable and separable manner; and a card whose side facing the movable iron piece is in contact with the pivoting arm of the movable iron piece, wherein the movable iron piece that pivots based on the excitation and degaussing of the electromagnet presses the card to drive a contact mechanism, and wherein at least one facing plane out of the facing planes of the one leg of the iron core and the pivoting shaft of the movable iron piece comprises a magnetic flux density reduction mechanism.
