Abstract

To provide a molded product manufacturing method which makes it possible to suppress variations in the forming quality of members being processed. This manufacturing method comprises a disposition step for disposing a member being processed (20) on a forming die (10), a supply step for supplying a bladder with a fluid above the member being processed, and a lowering step for lowering a bladder (30). The member being processed is sheet-shaped and has a greater area than an upper face of the forming die. The bladder is such that an opening of a rigid box is covered by a stretchable sheet-like member. In the supply step and the lowering step, a regulating member is used which, as the bladder lowers, prevents a region in which the bladder expands from protruding from a region in which the bladder makes contact with the member being processed.
