A rotary electric machine comprising: a stator comprising: a stator core that is configured by laminating in an axial direction a plurality of core sheets that are made of a magnetic material; and a stator winding that is mounted to said stator core ; and a rotor that is disposed coaxially inside said stator so as to have a magnetic air gap interposed, said rotor having a plurality of field poles, said plurality of core sheets each comprise: an annular core back portion ; a plurality of tooth portions that are arranged at a uniform angular pitch in a circumferential direction such that each protrudes radially inward from said core back portion; slot portions that are formed between adjacent teeth portions ; and flange portions that protrude circumferentially from a protruding end of each of said tooth portions; said plurality of core sheets comprise linked core sheets that comprise linking portions that protrude circumferentially from said flange portions so as to link together tip portions of said adjacent tooth portions; characterized in that : at least one sheet of said linked core sheets is formed such that a tooth tip portion shape is mirror-asymmetrical relative to a tooth central axis (A) that passes through a circumferential center of said tooth portions ; and said stator core is configured by laminating said linked core sheets such that circumferential positions of said linking portions are offset. a stator comprising: a stator core that is configured by laminating in an axial direction a plurality of core sheets that are made of a magnetic material; and a stator winding that is mounted to said stator core ; and a stator core that is configured by laminating in an axial direction a plurality of core sheets that are made of a magnetic material; and a stator winding that is mounted to said stator core ; and a rotor that is disposed coaxially inside said stator so as to have a magnetic air gap interposed, said rotor having a plurality of field poles, said plurality of core sheets each comprise: an annular core back portion ; a plurality of tooth portions that are arranged at a uniform angular pitch in a circumferential direction such that each protrudes radially inward from said core back portion; slot portions that are formed between adjacent teeth portions ; and flange portions that protrude circumferentially from a protruding end of each of said tooth portions; an annular core back portion ; a plurality of tooth portions that are arranged at a uniform angular pitch in a circumferential direction such that each protrudes radially inward from said core back portion; slot portions that are formed between adjacent teeth portions ; and flange portions that protrude circumferentially from a protruding end of each of said tooth portions; said plurality of core sheets comprise linked core sheets that comprise linking portions that protrude circumferentially from said flange portions so as to link together tip portions of said adjacent tooth portions; characterized in that : at least one sheet of said linked core sheets is formed such that a tooth tip portion shape is mirror-asymmetrical relative to a tooth central axis (A) that passes through a circumferential center of said tooth portions ; and said stator core is configured by laminating said linked core sheets such that circumferential positions of said linking portions are offset. at least one sheet of said linked core sheets is formed such that a tooth tip portion shape is mirror-asymmetrical relative to a tooth central axis (A) that passes through a circumferential center of said tooth portions ; and said stator core is configured by laminating said linked core sheets such that circumferential positions of said linking portions are offset. <EOS>
