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.

The curved inner surface of the die (80) varies in cross-sectional shape from one position to next along the axial direction of the die (80) at least in part along the axial direction. A ring magnet manufacturing method includes filling the magnetic powder into the cavity and producing the ring-shaped powder compact (100) by pressurizing the magnetic powder in the cavity in the axial direction by means of the lower and upper punches (91, 92) while applying a radially orienting magnetic field to the magnetic powder, and sintering the ring-shaped powder compact (100).
