PROBLEM TO BE SOLVED: To provide a laminated core which can simply couple adjacent split laminated cores without depending on welding, or a component such as a pin etc. SOLUTION: The laminated core is constituted by connecting annularly the split laminated core 20 constituted by laminating core sheets. The split laminated core 20 has a back yoke 22 and teeth 23 which extend radially from the back yoke 22. Superposed parts 25a, 26a are formed on the adjacent core sheets in the laminating direction. A groove 30 is formed at the one 25a of the superposed parts, and a projection 40 inserted into the groove 30 is formed at the other one 26a of the superposed part. Moreover, the outer peripheral shape of the projection 40 is formed substantially circular, and the inner peripheral shape of the groove is formed in an R shape along the outer periphery of the projection 40.
