PURPOSE:To prevent damage of a coil and fall off of a spacers, by forming stopper parts, adding flexible insulating plates in the spacers in the laminating direction of an iron core body, and positioning and holding the spacers with the stopper parts. CONSTITUTION:An iron core body 10 is formed with laminated iron cores 12. A coil 13 is provided around the body 10. Spacers 16 comprising a resin are inserted between both end surfaces of the iron core body 10 and the coil 13 so as to determine an interval between both parts. A stopper part 18, which positions and holds said spacer 16, is protruded. A flexible insulating plate 25 is added to said spacer 16 in the laminating direction of the iron core of the iron core body 10. The flexible insulating plate 25 is added to each spacer 16 in the insulating direction of the iron core of the iron core body 10 and each spacer 16 is forcibly inserted between the iron core body 10 and the coil 13 along both end surfaces of the iron core body 10. Therefore, dispersion in insulating thickness of the iron core body 10, dispersion in finish of the inner diameter of the coil and the like are absorbed by the flexibility of the insulating plate 25, and both spacers can be evenly inserted.
