Abstract
An instant photographic film unit includes a mask sheet having an image frame and two sheets, one of which has a photosensitive layer, laminated and bonded together, and a developing liquid container disposed in a predetermined position for supplying a developing liquid between the two sheets to produce an image. The mask sheer and the two sheets are bonded together in a predetermined laminated state, with at least one of the mask sheet and the two sheets being in the form of a continuous web. The continuous web is cut off into self-developed instant photographic film units of a predetermined length. A predetermined number of instant photographic film units are automatically stacked and placed in a film pack.
