Abstract: A method for punching an insulating film is composed of using plural divided punches having a clearance between each two of the divided punches. The clearance absorbs thermal expansion of the divided punches caused by receiving a heat from a heater. A punched insulating film is stuck to a lead frame by being pressed between the divided punches and the heater.
