PROBLEM TO BE SOLVED: To provide a transparent resin molding the transparency of which can vary with temperatures and to provide its use. SOLUTION: This molding is formed from a resin composition being one comprising a plurality of resins the temperature dependencies of the refractive indices of which are different from each other, wherein the difference of the refractive indices of the resins is at most 2×10-2 at least one temperature in the service temperature range. It is desirable that one component of the resin composition used to form the molding is at least one cycloolefin resin selected from the group consisting of (A-1) anα-olefin/cycloolefin random copolymer obtained from a 2-20Cα-olefin and a cycloolefin having a specified structure; (A-2) a ring-opening polymer or copolymer of the cycloolefin; (A-3) a product of hydrogenation of (A-2); and (A-4) a product of graft modification of (A-1), (A-2), or (A-3). The molding is applicable to free-standing screens and curtains.
