PROBLEM TO BE SOLVED: To provide a laminated core wherein winding of a coil around a magnetic pole center portion is performed without damaging an insulating film of the coil and the coil itself, a better space factor is obtained, and winding work is performed with better productivity. SOLUTION: In the laminated core in which split laminated cores 10 are connected through connecting portions 19, 20, corner portions 15, 16 of upper and lower ends of the magnetic pole center portion 12, and corner portions 17, 18 at a radial outside, and of upper and lower ends of a thickness direction of a magnetic pole tooth portion 13 are rounded, wherein the split laminated cores are formed by laminating by caulking split iron core members 21, 22 in which yoke strips are split for every magnetic pole.
