PROBLEM TO BE SOLVED: To provide an electromagnetic relay disusing braided wires for securing a current capacity of a main contact device. SOLUTION: A main contact device 2A and an arc contact device 3A are connected in parallel and are inserted into a power-feeding channel to a load. A sub contact device 4 is electrically independent of the main contact device 2A and the arc contact device 3A. The main contact device 2A is provided with a main fixed contact 27 fixed to a unit body 1 and a main contact spring 23 made of a leaf spring to which a main movable contact 25 coming in and out of contact with the main contact 27 is firmly fixed. Further, the arc contact device 3A and the sub contact device 4 are arrayed in adjacent zones in the unit body 1. The main contact spring 23 is extended along a direction in which the arc contact device 3A and the sub contact device 4 are arrayed. Therefore, the main contact spring 23 can be made in a large size in the unit body 1 and can be made large in cross section without increasing a spring constant, and braided wires are disused.
