Summary:A rotating electric machine stator is provided with: an iron core (10) having a yoke portion (111) having a recess portion (117) on the outer circumferential surface (12) thereof and a plurality of tooth portions (112) having a shoe portion (114); and a coil portion (11) wound around each of the tooth portions (112) with a first insulator portion (130) and a second insulator portion (120) interposed therebetween. The second insulator portion (120) is provided in a slot (113) between the tooth portions (112), is formed to be sheet-shaped and have electrical insulation properties, and has a projection portion (121) projecting from both ends of the iron core (10) in the shaft direction (Y). The first insulator portion (130) is provided with: a first projection portion (132) installed at bothends of the iron core (10) in the shaft direction (Y), having electrical insulation properties, making contact with the projection portion (121), and inserted into the recess portion (117); and a second projection portion (13
