PROBLEM TO BE SOLVED: To obtain a motor in which a coil has high insulation performance by eliminating or reducing voids inside a slot of a stator core. SOLUTION: The coil 3 is wrapped in insulating paper 4 opened to the opening part side of the slot 2 of the stator core 1 and inserted to the slot 2. After that, it is molded with an insulating resin 5. The coil 3 can be insulated in the slot 2 in a state of no void or little voids by preventing the occurrence of the voids such as cavities and holes since when the resin 5 intrudes into the slot 2, the air in the slot is discharged toward the opening part and there is no member for preventing the flow of the air. Dielectric strength is enhanced because of no void. Manufacturing processes and an amount of the insulating paper can be reduced. Consequently, the motor can be inexpensively obtained.
