PROBLEM TO BE SOLVED: To provide a small laminated core where a plurality of core sheets are integrated by engaging caulking parts, that provides proper flatness at its end phase, correcting rising of teeth of core sheets at the end phase. SOLUTION: A caulking part 17 of a first core piece 20 comprises a hole 21, and the caulking part 17 of a second piece 22 has a protruding part 23 on one side, while has a recess 24 on the side opposite to the protruding part 23. The protruding part 23 of the second core piece 22 is engaged with the hole 21 of the first core piece 20, while the protruding part 23 of the adjoining second core piece 22 is engaged with the recess 24 of the second core piece, thus the protruding part 23 and the recess 24 of the second core piece 22 are engaged each other in order, integrating a laminated core 8. Lifting of teeth 15 of such a first core piece 20 among the teeth 15 of the first core piece 20, as provided on the surface on the second core piece 22 side, is corrected by a drive part 25.
