PURPOSE: An electromagnetic relay is provided to obtain no chance that the NO contact is put in the conduction holding state, even if the coil is thermally expanded. CONSTITUTION: A electromagnetic relay(31) comprises a case(44) having an opening at one end thereof and covering the whole electromagnetic relay, a spool(32) with a coil as an electromagnet wound therearound, the spool including a first flange disposed inside the case and at an opened side of the case, and a second flange disposed at an inner part of the case, a fixed contact(38) disposed at a top end part of a fixed terminal extending to a position closer to the inner part of the case than the second flange of the spool, and a movable contact(37) disposed at a position closer to the inner part of the case than the fixed contact, the movable contact being brought into contact with or separated from the fixed contact by an attraction force of the electromagnet and a restoring force of a spring for supporting the movable contact, whereby a conduction state between a movable terminal conductively coupled to the movable contact and the fixed terminal is switched over, wherein the second flange has an end edge part facing the top end part of the fixed terminal, and a low strength part, which is low in rigidity and on which stress concentrates, disposed along a portion demarcating the end edge part of the second flange, and the fixed terminal is secured to the first flange.
