Abstract
A first separator to which a resin film is joined beforehand is set in a cavity formed between a lower die and an upper die of an injection molding machine. At the time of die locking by moving the upper die toward the lower die, in the case where the total thickness of the resin film and the first separator is larger than a predetermined dimension, the resin film is pressed by the lower die or the upper die, and thus, the resin film is deformed by compression within its elastic deformation range.
