An electromagnetic relay comprising: a contact block including a fixed contact portion provided with a fixed contact, and a movable contact portion provided with a movable contact brought into contact with and separated from the fixed contact; and a drive block configured to bring the movable contact into contact with the fixed contact and separate the movable contact from the fixed contact, the drive block including: an iron core including a body portion extending in one direction, and leg portions (820,830) extending downward from both ends in an extending direction of the body portion in a state in which the extending direction of the body portion conforms to a horizontal direction; a coil frame to which the iron core is fixed; a coil wound on the body portion of the iron core with the coil frame interposed therebetween; an armature arranged across the iron core from one leg portion to another leg portion and configured to swing on one end serving as an axis; and a movable body configured to move in association with a swing of the armature, the armature including: a support portion opposed to the one leg portion of the iron core to serve as the axis; a magnetic pole opposed to the other leg portion of the iron core; and an arm portion extending to connect the support portion and the magnetic pole and configured to cause the magnetic pole to swing on the support portion so as to come close to and separate from the other leg portion of the iron core, the movable body being attached to the arm portion and provided with a pressure projection for moving the movable contact, characterized in that the pressure projection is located on a line segment connecting a center of gravity of the support portion and a center of gravity of the magnetic pole. a contact block including a fixed contact portion provided with a fixed contact, and a movable contact portion provided with a movable contact brought into contact with and separated from the fixed contact;
