PROBLEM TO BE SOLVED: To provide a continuous manufacturing method of a stator core and a divided core block, which does not lower an electric characteristic, which lowers production costs and which can take out a divided core block in a separated state, and to provide a continuous manufacturing method. SOLUTION: In this stator core, a divided core block formed in such a way that flat rolled magnetic steel sheets 2 to 4 are laminated is fixed by steel sheet caulking parts and a plurality of stages of the divided core block are stacked by displacing the divided core block in the circumferential direction. The divided core block is composed of the rear-surface flat rolled magnetic steel sheet 2 which comprises steel-sheet caulking parts 21 and block caulking parts 22. In addition, the divided core block is composed of the intermediate flat rolled magnetic steel sheets 3 which comprise steel-sheet caulking parts 31. In addition, the divided core block is composed of the surface flat rolled magnetic steel sheet 4 which comprises steel-sheet caulking parts, block caulking parts 42 and block-caulking separation parts 43.
