PROBLEM TO BE SOLVED: To improve a release strength of a base material and a polyolefin layer by laminating a polyolefin resins layer made of a plurality of layers on a base material, and forming the polyolefin resin layers of an adhesive polyolefin resin layer at its side directed toward the base material. SOLUTION: A pattern layer 2 is laminated on an upper surface of a colored layer 4 as a base material, and transparent sheets 1a, 1b of two layers are laminated on the base material through an adhesive layer 3. The sheets 1a, 1b are constituted of a polyolefin resin layers of high crystallines such as polyethylene, polypropylene, polymethylpentene, polybutene, ethylene-propylene copolymer, propylene-butene copolymer or the like. Thus, an insufficiency of an adhesive force generating in the case of replacing a base material sheet from a polyvinyl chloride resin sheet to a polyolefin resin can be improved.
