摘要： In a rotary electric machine laminated core, a rotating shaft portion is disposed closer to an outer circumferential surface than an inner circumferential surface of a back yoke portion. A notch portion is disposed on at least one of first and second end portions of the back yoke portion so as to form a gap between a vicinity of the rotating shaft portion of a projecting portion and a recess portion when core segments are arranged in an annular shape or a circular arc shape. The first end portion and the second end portion of the back yoke portion are configured such that a predetermined gap that connects from the outer circumferential side to the inner circumferential side is formed between adjacent projecting portions and recess portions when the core segments are expanded rectilinearly such that magnetic pole tooth portions are parallel to each other.
