The present invention aims to provide a manufacturing device for heat exchanger fins that is capable of adjusting for differences between a number of punches and a number of through-holes or cutaway portions in an actual product without causing a metal strip to sag or having punches punch the same positions twice. As a solution, a mold () is provided with a plurality of punches () and a plurality of dies () that form a plurality of through-holes or cutaway portions along a conveying direction of a metal strip () and also includes a feeding apparatus () that feeds the formed plurality of through-holes or cutaway portions in the feeding direction in a single feeding operation, and a cutoff device () that cuts the metal strip () into predetermined lengths has an equal number of cutoff punches () to a number of the punches and dies disposed along the conveying direction of the metal strip (), includes a plurality of cutoff punch driving units () that respectively and individually operate the cutoff punches (), and also includes a control unit () that controls each of the cutoff punch driving units ().
