PROBLEM TO BE SOLVED: To provide a manufacturing method of a stacked stator core, with which the stacked stator core superior in shape accuracy and an electrical characteristic can be manufactured. SOLUTION: The method comprises a process of punching and forming a yoke of the stacked stator core as a belt-like yoke core piece 11 which shows a shape developed into a line shape, has coupling recesses 11a in a side edge, equivalent to an inner circumference 11i and planar arc-like caulking parts 11c bent along a winding direction are arranged at equal intervals from a metal plate; a process of engaging a caulking tongue piece of the ark-like caulking part into a caulking groove of the ark-like caulking part at a lower layer and caulking the connecting them, while the belt-like yoke core piece is wound spirally and is stacked so as to form a yoke stacked body; a process of punching and forming the magnetic pole core, having a coupling projection at a base end from the metal plate; a process of stacking a prescribed number of magnetic pole core pieces and caulking/connecting them and forming a magnetic pole stacked body, and a process of winding a wire on the magnetic pole stacked body, engaging the coupling projection into the coupling recess and coupling the yoke stacked body and the magnetic pole stacked body.
