There is provided a method for manufacturing a stator core for an axial air-gap electronic motor, in which core sheets are laminatedly fixed while being shifted with predetermined intervals. The method includes a step in which first side surfaces in the circumferential direction (first slot surfaces) of the first to nth (n is a positive integer) core sheets are blanked out of a mother sheetby moving first blanking puncheswith predetermined intervals via a first control means; and a second blanking step in which second side surfaces in the circumferential direction (second slot surfaces) of the first to nth (n is a positive integer) core sheets are blanked in succession by moving a second blanking punchwith predetermined intervals via a second control means
