PROBLEM TO BE SOLVED: To prevent cracking of a coil terminal holding part, when a coil terminal is held against the coil terminal holding part. SOLUTION: A coil terminal holding part 13 is formed integrally with a coil bobbin 3. A base part 20, which projects in an opposite direction to a main part 13a, is formed on a wall part 13b of the coil terminal holding part 13 from the lower end to approximately the center of the wall part 13b. A through- hole 21 into which a coil terminal 14 is pressfitted and an open groove 22 which is open to the side face of the base part 20 along the pressfitting direction of the coil terminal 14 and communicating with the through-hole 21 are provided near each end of the base part 20. Therefore, the connecting piece 14a of the coil terminal 14 is previously curved, before being pressfitted into the through- hole 21 and is inserted into the open groove 22, whereby the coil terminal 14 can be pressfitted into the through-hole 21 in the coil terminal holding part 13. Thus, no excess stresses are applied to the coil terminal holding part 13, and cracking of the coil terminal holding part 13 can be prevented.
