PROBLEM TO BE SOLVED: To manufacture a laminated core which improves the productivity, while keeping the form accuracy properly and is also strong in mechanical strength by winding a band-shaped core piece in piles. SOLUTION: In the method of manufacturing a laminated core which winds the band-shaped core pieces 10 and 11 spirally and calking them for lamination, plural sheets of band-shaped core pieces 10 and 11, where split core pieces 14 and 15, divided for each of two or more magnetic poles 16 and 17, are coupled to each other via rotatable couplings 12 and 13, are wound in piles so that each magnetic pole 16 and 17 lie on top of the other above and below, with the positions of the couplings 12 and 13 of the band-shaped core pieces 10 and 11 lying on top of the other above and below slid. There are cases, where they look to the same tangent direction and a where the band-shaped core pieces 10 and 11 are directed to the tangent directions at different angles with respect to the laminated core 18 where they are wound.
