Abstract
An electromagnetic relay includes a moving member, a yoke, a guide member, and a movable iron core. The yoke includes a plate portion and a yoke hole. The guide member is disposed in the yoke hole. The movable iron core is connected to the moving member. The movable iron core includes a tubular portion. The tubular portion includes a first end surface and a second end surface. The tubular portion is disposed in the guide member. The plate portion includes a first surface and a second surface. In a case where the moving member is located at the closed position, the first end surface is located within a range from a first position to a second position. The first position is a position corresponding to the first surface. The second position is located at a center of the first surface and the second surface.
