PROBLEM TO BE SOLVED: To provide a manufacturing method for simplifying a manufacturing method of stator where a stator coil having a crank type coil end is formed in a shape developed in the circumferential direction before being received in the slot of a stator core. SOLUTION: Slot receiving conductor portions 103, i.e. coil conductor portions being received in a slot, are joined by pressure welding while touching the distal end faces 105 thereof tightly and then applied with an insulation coating thus manufacturing a circumferentially developing coil. Consequently, a circumferentially developing coil having a coil end of complicated profile and a short projection length in the axial direction can be manufactured easily.
