An electromagnetic relay is composed of a coil wound around magnetic core, a U-shaped magnetic pole member connected to an end of the magnetic core and provides a space, a yoke member connected to the other end of the magnetic core, an armature movably connected to the yoke and disposed in the space, a permanent magnet secured to the armature near the magnetic core and supporting member supporting the armature. Since the permanent magnet is disposed near the magnetic core, magnetic flux of the permanent magnet can be utilized effectively and, therefore, the size of the relay can be reduced.
