Electromagnetic relay

An electromagnetic relay (1) is formed by assembling a drive part (30), mobile body (50) that moves when the drive part (30) is driven, and a plurality of contact mechanisms (60, 70) that switch the contact and separation of contacts (61d, 62d, 71d, 72d) by the movement of the mobile body (50) in a body (40). Furthermore, a partition wall (21) is provided inside a case (20), which is fitted over the body (40), and a latching part (42) is provided in a location on the body (40) corresponding to the partition wall (21). In the state where the case (20) is fitted over the body (40), the front end of the partition wall (21) is latched to the latching part (42).
