Summary:To suppress reduction in magnetic efficiency of an electromagnet, in an electromagnetic relay.SOLUTION: An electromagnetic relay comprises a case, a contact device, a drive device, and a coil terminal. The case includes a first wall, and a second wall opposed to the first wall in a first direction. The contact device includes a first fixing terminal, and a second fixing terminal arranged apart from the first fixing terminal in the first direction. The drive device is housed in the case. The drive device includes a coil and a yoke. The yoke has a U-shape and surrounds the coil in a direction different from the first direction. The coil terminal is connected to the coil and drawn out to the exterior of the case from the first wall of the case.SELECTED DRAWING: Figure 3 【課題】電磁継電器において、電磁石の磁気効率の低下を抑制する。【解決手段】電磁継電器は、ケースと、接点装置と、駆動装置と、コイル端子とを備える。ケースは、第１壁と、第１壁と第１方向に対向する第２壁とを含む。接点装置は、第１固定端子と、第１固定端子と第１方向に離れて配置された第２固定端子とを含む。駆動装置は、ケースに収容される。駆動装置は、コイルと、ヨークとを含む。ヨークは、Ｕ字形状を有し、コイルを第１方向と異なる方向から囲む。コイル端子は、コイルに接続され、ケースの第１壁からケースの外部に引き出される。【選択図】図３
