An electromagnetic relay comprising: a fixed contact holder extending in a predetermined direction and provided with a fixed contact at one end portion thereof; a moving contact holder also extending in the predetermined direction, arranged to face the fixed contact holder, provided with a moving contact at one end portion thereof, and configured to move between a closed position where the moving contact comes into contact with the fixed contact and an open position where the moving contact goes out of contact with the fixed contact; an electromagnetic device configured to displace the moving contact holder such that the moving contact moves back and forth between the closed position and the open position; and a magnet (17, 18) arranged perpendicularly to an opening/closing direction of the fixed contact and the moving contact, a stretch space in which an arc generated between the fixed contact and the moving contact is stretched being provided, in the predetermined direction, beyond respective tips of the fixed contact holder and the moving contact holder, characterized by the stretch space being provided to face one surface, out of two surfaces (12a, 12b) of, the fixed contact holder along the thickness thereof, the one surface of the fixed contact holder being located opposite from the other surface thereof where the fixed contact and the moving contact come into contact with each other, the stretch space being provided to face one surface, out of two surfaces (14a, 14b) of, the moving contact holder along the thickness thereof, the one surface of the moving contact holder being located opposite from the other surface thereof where the fixed contact and the moving contact come into contact with each other. a fixed contact holder extending in a predetermined direction and provided with a fixed contact at one end portion thereof; a moving contact holder also extending in the predetermined direction, arranged to face the fixed contact holder, provided with a moving contact at one end portion thereof, and configured to move between a closed position where the moving contact comes into contact with the fixed contact and an open position where the moving contact goes out of contact with the fixed contact; an electromagnetic device configured to displace the moving contact holder such that the moving contact moves back and forth between the closed position and the open position; and a magnet (17, 18) arranged perpendicularly to an opening/closing direction of the fixed contact and the moving contact, a stretch space in which an arc generated between the fixed contact and the moving contact is stretched being provided, in the predetermined direction, beyond respective tips of the fixed contact holder and the moving contact holder, characterized by the stretch space being provided to face one surface, out of two surfaces (12a, 12b) of, the fixed contact holder along the thickness thereof, the one surface of the fixed contact holder being located opposite from the other surface thereof where the fixed contact and the moving contact come into contact with each other, the stretch space being provided to face one surface, out of two surfaces (14a, 14b) of, the moving contact holder along the thickness thereof, the one surface of the moving contact holder being located opposite from the other surface thereof where the fixed contact and the moving contact come into contact with each other.
