A coil alignment device includes: a plate-shaped first jig having a plurality of grooves arranged along a circumferential direction so as to extend toward a radial-direction outer side; and a second jig that can contact with a segment coil inserted in the first jig. Each groove includes a storage portion extending along a radial direction and having a first length so that leg portions of the segment coils can be stored side by side in the radial direction, and a guiding portion extending from the storage portion toward the radial-direction outer side, and has a first shape so that, using, as a fulcrum, one leg portion inserted in the storage portion, the other leg portion is movable toward the storage portion. The second jig is movable to press the segment coil from a radial-direction side and store the other leg portion into the storage portion.

A rotating electrical machine can increase the strength of divided cores and, in addition, can achieve both a reduction in iron loss and a high rigidity of the divided cores. The stator of the rotating electrical machine includes a stator core having radially divided cores arranged in a ring, each divided core being a laminate of magnetic steel sheets. Each divided core has a swaged portion in which the laminated magnetic steel sheets are bonded by swaging. The swaged portion is disposed in a core back portion, which is in contact with core back portions of divided cores located on both sides of the divided core at a position whose distance from an outer periphery of the core back portion is within &#x2153; of a radial length of the core back portion.
