An electromagnetic relay structure which includes a bobbin 1 having a coil 5 wound therearound. A coil terminal 6 is electrically connected with an end 5a of the coil 5. A base 4 is insert-formed with a terminal 8, 9. The coil terminal 6 has a first end firmly attached to a flange 1c of the bobbin 1 and a second end connected to the terminal 8, 9. A projecting piece 6a is formed in a generally central portion of the coil terminal 6. The projecting piece 6a is bent with an end 5a of the coil 5 twined therearound, to thereby support the end 5a of the coil 5. Another flange 1a of the bobbin 1 is fixed to the base 4 by fitting a projecting rod 1b of the flange 1a to a fitting groove 4a of the base 4.
