A method is provided for manufacturing a stator coil for a rotary electric machine, which is formed by winding up a plurality of phase wires. The method includes a shaping step for shaping a plurality of shaped wire members from electrically conductive wires, an integrating step for integrating the plurality of shaped wire members with each other to form an integrated body, and a winding-up step for winding the integrated body about a core member to form a wound body. At the winding-up step, curve forming is performed by plastically deforming turn portions of the integrated body into a curved shape, during conveyance of feeding the integrated body to the core member.
