PROBLEM TO BE SOLVED: To provide a form coil bobbin that facilitates assembly into form coils without increasing the number of components. SOLUTION: This bobbin 20 has a first surface member 20a, which contacts the inside circumferential surface of a yoke cylindrical body 15, and a second surface member 20b, which is provided to face the first surface member 20a to form an accommodation space part 20c for accommodating form coils 17 between the first surface member 20a and itself. Pole core insertion holes 20e, into which boss part 18a of pole cores 18 is inserted, are formed to correspond to the coil parts 17a of the form coils 17 in the first surface member 20a and the second surface member 20b. A plurality of claw pieces 20f, which are bent inside the pole core insertion hole 20e and inserted between the inside circumference of the coil parts 17a and the boss part 18a of the pole core 18 on the circumferential edge of the pole core insertion hole 20e of the second surface member 20b.
