Provided is an electromagnetic relay which does not require a braided wire for securing a current capacity of a main contact unit. The electromagnetic relay includes a main contact unit 2 A inserted into a power supply path to a load and an arc contact unit 3 A connected in parallel to the main contact unit 2A. An auxiliary contact unit 4 is electrically independent of the main contact unit 2 A and the arc contact unit 3A. The main contact unit 2 A includes a main fixed contact 27 fixed to a frame body 1 and a main contact spring 23 made of a leaf spring and fitted with a main mobile contact 25 which is attached to and detached from the main fixed contact 27. The arc contact unit 3 A and the auxiliary contact unit 4 are arranged adjacent to each other. The main contact spring 23 extends in a direction in which the arc contact unit 3 A and the auxiliary contact unit 4 are arranged. Therefore, the main contact spring 23 can be formed with a large length in the frame body 1 and the sectional area can be enhanced without increasing a spring constant, thereby not requiring a braided wire.
