Abstract: A stator includes a hollow cylindrical stator core and a stator coil formed of a plurality of electric conductor segments. Each of the electric conductor segments includes, at least, an in-slot portion received in a corresponding slot of the stator core and a protruding portion that protrudes from the in-slot portion outside of the corresponding slot. Each of the electric conductor segments also has an insulating coat covering its outer surface. For each intersecting pair of the protruding portions of the electric conductor segments, at least one of the two protruding portions of the intersecting pair has an indentation formed in a side face thereof radially facing the other protruding portion at the intersection of the two protruding portions. Further, a thickness of the insulating coats at the indentations is substantially equal to a thickness of the insulating coats at the in-slot portions of the electric conductor segments.
