Abstract

A method that can produce a high-performance stator by providing only an upper or lower fixed piece for latching a coil on an insulator and thus effectively suppressing loosening of the coil winding wire when resin is injected while improving the production efficiency of the insulator. The method includes producing an intermediate by disposing a coil around an insulator, which includes a tubular portion, a flange at one end thereof, and a fixed piece that, when the insulator is loosely fit around the tooth, extends in the radial direction of the tooth from an end side of the flange corresponding to an upper or lower end face of the tooth, and has a coil latching claw, and loosely fitting the insulator with the coil around the tooth; and placing the intermediate in a die and injecting resin from around a region where the coil is latched by the fixed piece.
