Abstract: An electromagnetic relay includes a fixed contact module including a fixed contact, a movable contact module including a movable contact disposed to face the fixed contact, an armature formed of a magnetic material and configured to move the movable contact module to bring the movable contact into and out of contact with the fixed contact, and an electromagnet configured to generate a magnetic field to move the armature. At least one of the fixed contact module and the movable contact module includes a joint at which different components are joined by riveting, and a film with a thermal conductivity higher than, the thermal conductivity of the fixed contact module and the movable contact module is formed on at least one of the fixed contact module and the movable contact module including the joint.
