Abstract:
The present invention comprises: an iron core (110) having an annular core back (111) and a plurality of teeth (112) formed apart from each other in the circumferential direction (Z) so as to protrude from the inner circumferential surface (11A) of the core back (111); a coil (3) wound on the teeth (112) with an insulator (2) therebetween; and a mold resin part (5) that covers the iron core (110) and the coil (3). The core back (111) is formed separately at least at one place in the circumferential direction (Z). The insulator (2) has, at two or more places in the circumferential direction (Z), projections (21) that each project outward (X1) in a radial direction (X) from the outer circumferential surface (11B) of the core back (111). The mold resin part (5) does not cover projection surfaces (21) along the axial direction (Y) and located outward (X1) of the projections (21) in the radial direction (X).
