A method for manufacturing a stator core for an axial air-gap electronic motor is provided, in which core sheets are laminated and fixed while being shifted with predetermined intervals. The method includes a step in which first side surfaces (361) in the circumferential direction (first slot surfaces 25) of the first to nth (n is a positive integer) core sheets (23) are blanked out of a sheet by moving first blanking punches (360) with predetermined intervals via a first control means (700A); and a second blanking step in which second side surfaces (46) in the circumferential direction (second slot surfaces 26) of the first to nth (n is a positive integer) core sheets (23) are blanked in succession by moving a second blanking punch (460) with predetermined intervals via a second control means (700B).
