Abstract:
[Problem] To enable the winding space factor of a rotary electric machine to be improved by making bobbins thinner. [Solution] A rotary electric machine (1) has bobbins (6) that are attached to protrusions (18) of a laminated core (5) of a stator (2). Each bobbin (6) is equipped with a square frame-like body section (21) around which a coil wire (7) is wound. The body section (21) has thin film bodies (22a), which are made of an insulating material, on one set of two facing side surfaces (21L, 21R) among the four side surfaces (21U, 21D, 21L, 21R) thereof, and has resin sections (23A, 23B) on the other set of two facing side surfaces (21U, 21D).
