PROBLEM TO BE SOLVED: To provide an electromagnetic relay in which a coil bobbin and a cover can be assembled with good workability. SOLUTION: Two pieces of positioning projections 24a are installed at the left side flange part 24 of a coil bobbin 22 housed in a first yoke 16 of cylindrical shape, two pieces of positioning holes 46a are installed at a second yoke 46 to be inserted in the left side opening of the first yoke 16, and four pieces of positioning holes 64 are formed at the left side cover 60 to cover the left side opening of the first yoke 16. Since the positioning projection 24a of the left side flange part 24 can be inserted into the positioning hole 46a of the second yoke 46, and then, inserted into the positioning hole 64 of the left side cover 60, the left side flange part 24, the second yoke 46, and the left side cover 60 can be positioned automatically, and the coil bobbin, the cover, and the yokes can be assembled with good workability.
