A coil assembly consisting of a permanent magnet arranged in the center of a U-shaped iron core around which a coil is wound, and a coil assembly arranged such that both ends thereof fit with both magnetic pole parts of the iron core. A movable contact spring block includes an armature, a hinge spring that causes the armature to perform a tilting motion, and a movable contact spring disposed near the armature, which are integrally fixed by an insulating fixture, and a fixed contact portion and an external lead-out terminal are installed. an insulator base provided therein, and a protrusion at the center of the armature is attached to one end surface of the permanent magnet so that the coil assembly is fixed to the insulator base and the movable contact spring block is tiltable. In the electromagnetic relay, the hinge spring is fixed to a part of the external lead-out terminal and is used as a fulcrum for the tilting movement of the armature, and the hinge spring is fixed to the movable contact spring facing the fixed contact part. An electromagnetic relay characterized in that a heat radiation part is provided on the opposite side of the movable contact part so as to sandwich the movable contact spring. 2. An electromagnetic relay characterized in that the heat radiating portion according to claim 1 uses a flat heat radiating plate. 3. An electromagnetic relay characterized in that the heat radiation part according to claim 1 uses a heat radiation plate in which a notch is formed.
