Rotary electric machine, crank-shaped continuously winding coil, distribution winding stator and forming method thereof

A crank-shaped continuous winding coil, wherein a conductive wire of a rectangular shape in cross-section and having an insulating coated layer is wound for plural times by superposing both side surfaces of the conductive wire corresponding to the rectangular shape, and broad surfaces in width size corresponding to plural pieces of the conductive wires vertical to the superposed side surfaces are formed, and comprises:

• a winding coil formed in parallel with a part of the broad surface;
• terminal portions of both ends of the winding coil extending on the straight line in parallel in the same direction as the parallel direction in the broad surfaces of both sides of the winding coil;
• and
• a crank shape formed by shifting a position by a width size of the broad surface along the broad surface without being accompanied with twisting on rough crowns of both ends of the winding coil,
• wherein the crank shape is formed by shifting a position by a width size of the broad surface along the broad surface without being accompanied with twisting, so that the terminal portions of the both ends are disposed to approach the width direction by the shift of the position of the crank shape.
