Abstract:
An electromagnetic relay includes a contact part including a fixed contact and a movable contact, the movable contact being displaceable in an approaching/separating direction with respect to the fixed contact; a drive part including a coil, a movable core, and a fixed core, the movable core being connected to the movable contact via an axial core, and the fixed core including a first plate member having a through hole through which the axial core is inserted and a second plate member that encapsulates the coil; and a permanent magnet polarized in a direction substantially perpendicular to the approaching/separating direction. The first plate member or the second plate member includes an extension part that extends toward the contact part, the extension part being configured to hold the permanent magnet.
