PROBLEM TO BE SOLVED: To provide a polishing resin molding of excellent polishing performance and strength, capable of preventing performance from being deteriorated even when formed into a thin polishing film, and capable of reducing deformation or reduction in strength through use, to allow a long time. SOLUTION: The polishing film is kneaded with at least one kind of polishing particle having 2 or more of Moh's hardness, a pyrolytic temperature or melting point is 400°C or more in a polymer constituting the polishing film, and the tensile strength of the polishing film is 500 MPa or more.
