A stator includes annular segment assembly portions of phases wound on a stator core in a distributed winding manner. The annular segment assembly portion of each phase includes segment coils that are each formed in a coil shape by connecting conductor segments to each other. An annular protrusion-equipped electrical insulation sheet is inserted between two conductor segments adjacent to each other in the radial direction in a turn portion-side coil end portion that is formed of portions of the segment coils which portions are protruded to an outer side from an end surface of the stator core in the axial direction. The protrusion-equipped electrical insulation sheet has a protrusion that is provided on an end edge of an annular main body portion on the side opposite to the stator core side in the axial direction so that the protrusion is protruded in the axial direction from the end edge. |
