Electromagnetic relay
 The electromagnetic relay is provide with a spring fixing part which fixes a signal contact spring, an earth contact spring and a spring connection portion to a board, and an armature made of a magnetic member and arranged to be rockable with a position matching with the spring fixing part. The armature is provided with a first end portion which presses the signal contact spring against signal fixed contacts and a second end portion which presses the earth contact spring against an earth fixed contact. The armature and each of the movable portions are arranged such that torques acting on the armature cancel one another by a repulsion of each of the contact springs when the signal contact spring and the earth contact spring are pressed against the board.
