Original Abstract Submitted
A stator includes: a stator core that is shaped in a tubular form and has a plurality of slots; and a plurality of conductor segments that are inserted into the slots and are electrically connected with each other to form a stator coil. Each conductor segment has: an electrical conductor that is shaped in a linear form; an electrical insulation film that covers a periphery of the electrical conductor; a plurality of capsules that are hollow and are dispersed inside the electrical insulation film; and a bend that forms a bent-back shape on the conductor segment at an end portion of the stator core which faces in an axial direction. Among the plurality of capsules, capsules located at an outer periphery of the bend and capsules located at an inner periphery of the bend are respectively shaped in an ellipsoid form at each of the plurality of conductor segments.
