Stator of electric rotating machine

A stator of an electric rotating machine comprising:

• a stator core having slots formed at an inner periphery thereof along a circumferential direction thereof;
• and
• a stator winding constituted by conductive wires wound on said slots
• said stator winding including in-slot portions accommodated in said slots and turn portions each connecting each adjacent two of said in-slot portions outside of said slots,
• said stator core including a core member having at least three first tooth portions extending in a radial direction of said stator core and a core back portion integrally connecting said first tooth portions at a radially end side thereof,
• said core member being configured such that each of said first tooth portions folded toward said core back portion is capable of unfolding to extend between a corresponding adjacent two of said in-slot portions when said core member is at a predetermined axial position with respect to said stator winding.
