PROBLEM TO BE SOLVED: To provide a method for easily forming a fine unevenness of complicated shape on the surface of a molded material of a thermoplastic resin, and to provide a molded material of the resin formed by this method. SOLUTION: The uneven pattern is formed on a part of the molded material, that is composed of the thermoplastic resin, by radiating an active energy ray on a part of the above molded material without forming a film of a radiation- sensitive resist composition, and then by brining a solvent into contact with the surface of this molded material to dissolve a part of the molded maturely of the thermoplastic resin. |
