<p>An electromagnetic relay capable of having desired operating characteristics by a simple and inexpensive structure despite the fact that the thickness thereof is small. A movable iron piece (20) is rotated by magnetizing or demagnetizing an electromagnet to elastically deform a movable contact piece (43) through a card (21) to open and close a movable contact (46) from and to the fixed contact of a fixed contact piece. The movable iron piece (20) comprises a card pressing part (36) capable of pressing the card (21). The card (21) comprises a contact piece pressing part (37) capable of pressing the movable contact piece (43) by rotating around the pivot. At least either of the movable iron piece (20) and the card (21) comprises a pressing position changing part which when the movable iron piece (20) is rotated, makes the card pressing part (36) perform the transmission of a force from the movable iron piece (20) to the card (21) after the transmission is performed at a position apart from the pressing position where the pivot is pressed by the card pressing part (36) of the movable iron piece (20).</p>
