An in-slot conductor part of a stator winding of a rotary electric machine has multiple in-slot conductors disposed in multiple slots. In each of the multiple slots a plurality of the in-slot conductors are disposed in a line in the depth direction of the slot, in the coil end parts each of the multiple coil end conductors has a root part led out through a slot opening at one of the end faces of a stator core in substantially the same direction as the extension direction of the in-slot conductors and a connecting part disposed farther from the end face of the stator core than this root part and bent so as to form a bridge between two root parts. At each of these slot openings, the root parts continuous with the in-slot conductors inserted into the slot are disposed in a line in the depth direction of the slot and form a root part line, on either side of these root part lines are formed cooling passages extending along said one of the end faces in the depth direction of the slot, on the outer side of the root part lines an end cylindrical part formed by overlapping connecting parts is formed, and on this end cylindrical part and covering at least the outer face thereof is disposed an insulating member.
