PROBLEM TO BE SOLVED: To solve the problem that, in a conventional stator, when winding a coil around a tooth part of a core and a tooth part of an insulator, the tooth part of the insulator may be circumferentially deviated relative to the tooth part of the core.SOLUTION: A stator 10 comprises: an annular core 60 including a plurality of first teeth (a tooth part of the core) protruding radially inwards; and an annular insulator 70 disposed on an end face of the core 60 and formed integrally. The insulator 70 includes a plurality of second teeth 71 (a tooth part of the insulator) laminated on the plurality of first teeth of the core 60, and a plurality of protrusions 75 protruding from the insulator 70 to the side of the core 60 and fitted with a groove part formed in the core 60. The plurality of protrusions 75 are disposed, respectively, in regions A-F defined by one of the first teeth 62 (the tooth part of the core) and the peripheral part thereof. |
