PROBLEM TO BE SOLVED: To prevent an armature from being inverted even if separated from a permanent magnet due to impact. SOLUTION: This electromagnetic relay has a projecting part 50 for suppressing the motion of an armature 4 on an armature block 5 composed of an insulator for holding the armature 4 and a recessed part for suppressing the motion of the armature 4 inside a cover corresponding to the projecting part 50. A space (x) between the projecting part 50 and the recessed part in the longitudinal direction (X direction) of the armature 4 is setδ<x<D, where a displacement in the X direction of the projecting part 50 when the armature 4 falls on the permanently closed side (opened side) isδand a displacement in the X direction of the projecting part 50 when the armature 4 separates from a permanent magnet 9 by a distance (d) is D.
