Electromagnetic relay including an insulating base housing, an operating electromagnet arranged on the base housing and a case covering the base housing and electromagnet. A movable contact and a fixed contact are attached to the base housing. The electromagnet includes a flat-plate-form yoke, a winding frame and an armature. The base housing includes a protrusion protruding upward in a vicinity of a first leg of the yoke. The winding frame includes an extension extending from a winding body on a side of the first leg, and which has an upper portion positioned at least above the first leg. The upper portion includes a recess which extends parallel to a direction of extension of the body of the yoke. The armature has a projection protruding upward on the upper end of the pivoting shaft. The projection is positioned inside a space defined by the recess of the winding frame and the protrusion of the base housing. With such a construction, pivoting of the armature is not affected by dimensional error or deformation of the base housing or the case.
