Abstract: A rotating electrical machine stator and a method for manufacturing a rotating electrical machine stator with high productivity. A rotating electrical machine stator includes a stator core having a slot; and a coil having a leg part including a held-in-slot part held in the slot and a portion extending from the held-in-slot part, and a resin foam is provided between an inner surface of the slot and an outer surface of the held-in-slot part facing the inner surface of the slot. The coil is formed by joining together a plurality of segment conductors each having a joint part, and a conductive joint material is disposed between a pair of joint parts facing each other in the slot.

Abstract: The stator is provided with a first joint part provided so as to extend in a radial direction as viewed in a rotation axis line direction; and a second joint part provided at a location corresponding to a fastening member and provided so as to extend in the rotation axis line direction so as not to overlap the fastening member.
