<p>It is to provide an electromagnetic relay that can perform the return operation of a movable iron piece quickly, free from a fear of welding the contact.</p><p>In the electromagnetic relay, an iron core (37) is penetrated through a through hole (42) formed on the bottom surface of the aluminum case and coil is wound around the shaft of the protruding iron core. Through applying a voltage to the coil for magnetization and stopping the voltage for demagnetization, a contact mechanism is driven with a movable iron piece that is going and returning, attracted by and separated from a magnetic pole portion of the iron core (37). In particular, a slit (43) for preventing generation of eddy current is provided on the opening end of the through hole.
