PROBLEM TO BE SOLVED: To provide a laminated core wherein divided laminated cores are strongly connected in the circumferential direction to be freely discharged from a press molding device without getting out of shape at handling, furthermore expansion function in the circumferential direction and prevention of the occurrence of cogging can be attained, and to provide a manufacturing method therefor. SOLUTION: The divided laminated cores 11 are formed by laminating the predetermined number of a first divided core piece 14 wherein a first and a second projection parts 18, 19 are formed in the circumferential direction at the clockwise and radially outside end of a circular arc shaped divided yoke piece 17 and at the counterclockwise and radially inside end of the divided yoke piece 17, and the predetermined number of a second divided core piece 15 wherein a third and a fourth projection parts 21, 22 are formed in the circumferential direction at the clockwise and radially inside end of a circular arc shaped divided yoke piece 20 and at the counterclockwise and radially outside end of the divided yoke piece 20. The connection parts 12, 13 of the adjacent divided laminated core 11 are formed by the first to fourth projection parts 18, 19, 21, 22 laminated in the predetermined numbers, and first to fourth recessed parts 27 to 30 to be formed by these projection parts.
