PROBLEM TO BE SOLVED: To provide an electromagnetic relay in which an appropriate magnetic circuit can be established. SOLUTION: The electromagnetic relay includes a center yoke 16 which is formed in a cylindrical shape with both ends open and in which a bobbin assembly 20 is housed in the cylinder, a left side yoke 46 which is inserted in a level difference part 17 of inner periphery of left end aperture of the center yoke 16 and fastened by a caulking process part 18, and a right side yoke 47 which is inserted in a level difference part 17 of inner periphery of right aperture part and fastened by a caulking process part 18. A plunger axle 51 of a plunger assembly 50 installed on the bobbin assembly 20 is inserted in the left side yoke 46, and a plunger 52 is housed in the inner cylinder portion 47b of the right yoke 47. Since the center yoke, the left side yoke, and the right side yoke can be established at an optimal thickness corresponding to the function of these, an appropriate magnetic circuit can be established.
