PROBLEM TO BE SOLVED: To provide a laminated core excellent in dimensional accuracy which can be manufactured accurately and inexpensively with high production efficiency, and to provide its manufacturing method. SOLUTION: The manufacturing method of a laminated core excellent in dimensional accuracy comprises a process for laminating a plurality of soft magnetic steel plates obtained by punching, a process for impregnating the laminate with thermosetting adhesive, a process for molding the laminate by constraining it with a molding jig using a fluororesin coating plate as a mold releasing material, and a process for drying and baking the laminate constrained by the molding jig. Alternatively, the manufacturing method is provided, between the process for laminating soft magnetic steel plates and the process for impregnating the laminate with thermosetting adhesive, with a process for temporarily fixing the laminate by coating the side face thereof partially with adhesive under a state where the laminate is molded by being constrained with the molding jig and then drying and baking the laminate.
