摘要： PROBLEM TO BE SOLVED: To provide a can, wherein a suitable code mark in response to the structure of the external surface, is formed. SOLUTION: In this can, a transparent coated film 4 is formed on the external surface of the can body. Then, a code mark 6, wherein one section of the transparent coated film 4 is engraved with a laser beam in the range where the code mark 6 does not reach the lower layer 3 of the transparent coated film 4, is applied on the external surface of the can body. Also, on the can bottom section, a transparent coated film which is directly formed on the surface of the base material of the can body, is provided. In this case, a code mark wherein one section of the transparent coated film of the can bottom section is engraved with a laser beam within a range that the code mark does not reach the base material, is applied on the bottom section of the can body. In addition, at least on the outer peripheral surface of the can body made of a metal, a decorative resin film wherein on the lower surface of a transparent thermoplastic resin film, a printed layer and an adhesive layer are formed, and on the other surface, a transparent coated film is formed, is affixed with an adhesive to form a laminated can. Then, one section of the lower layer of the transparent film is heated and evaporated by emitting a laser beam in a manner to transmit the transparent film, and the transparent film is partially raised to be approx. flush with the transparent coated film, and thus, the mark is formed.
