Zusammenfassung:	PURPOSE:To provide a can body in which patterns formed on the outer surface of a can trunk part by a high temperature treatment are hard to be scraped. CONSTITUTION:On a biaxially oriented polyethyleneterephthalate(OPET) film 12, a printed surface 15 is formed by printing in use of ink made of pigment dispersed in synthetic resin binder and, on the printed surface 15, a thermosetting epoxy resin adhesive layer 16 is formed. A printed OPET film 14 is thermal- bonded on a tin-plated superficial treatment steel sheet 12 via the adhesive layer 16 and then patterns are made on the side to be an outer surface of the can trunk. The surface having the patterns are directed to the side of an outer surface, and both end parts 13 of the superficial treatment steel sheet 12 are welded together so as to be a can trunk part. After giving a neck-in process and a flange process to both end parts of the can trunk part, a bottom lid and a top lid are subjected to a double-wind clamping, thus forming a can body.
