PROBLEM TO BE SOLVED: To bond an insert film along the shape of molding resin by using a non-stretched degradable plastic film for a base sheet for an insert film of specified thickness having at least a pattern layer formed on the base sheet. SOLUTION: A pattern layer 3 is formed on a base sheet 2 formed by using a non-stretched film of thickness of 200μm or less composed of biodegradable plastic to be degraded by microbes, or of photodegradeable plastic film to be degraded by the beams such as ultraviolet rays by using a color ink containing polyvinyl resin, polyamide resin, polyester resin or the like as a binder and a pigment or a dye of suitable color as a coloring agent. The film can be bonded on the surface of an insert molded product without being broken and also can be preformed into various shapes by vacuum molding inside or outside a mold by the arrangement.
