Rotating electrical machine

A rotating electrical machine comprising:

• a stator core including a plurality of rectangular conductors arranged in a slot;
• a first coolant flow path;
• and
• a second coolant flow path,
• wherein each rectangular conductor includes a specific shape portion and normal shape portions that are different from the specific shape portion and arranged with the specific shape portion interposed therebetween, and the specific shape portion has a relatively small thickness dimension in one direction orthogonal to a longitudinal direction of the rectangular conductor, and a relatively large thickness dimension in another direction orthogonal to the longitudinal direction,
• wherein the plurality of rectangular conductors are juxtaposed in the slot so that a plurality of the specific shape portions are adjacent to each other, and the first coolant flow path is formed between the normal shape portions of the plurality of rectangular conductors, and
• wherein the second coolant flow path is formed between an inner wall of the slot and the specific shape portions of the plurality of rectangular conductors.
