Abstract

The coil ends in a rotating electric machine are to be made smaller in size. A stator coilinserted into a slotin a stator of a rotating electric machine is formed with segment coilsconnected to one another. In the stator coil, the segment coilseach include an insulating coated portion coated with an insulating coating, and a slitor a recess is formed in the insulating coated portion of each of the segment coilsat a coil end. The slitor the recess is preferably formed between a diagonal conductor portionD and a conductor-end straight portionE of each segment coil
