Abstract
A press forming method uses a press forming apparatus for forming a film formed product as a formed film of a solid polymer electrolyte fuel cell. The method includes the step of trimming, in the state where a film material is held between a first die and a holder, by moving a second die closer to the first die to cut the film material using a trimming blade provided for the second die. A blade edge of the trimming blade includes two inclined blade edges inclined toward a proximal side of a blade part from the center to both ends of the blade part in the direction in which the blade part extends.
