PROBLEM TO BE SOLVED: To provide a recyclable paper roll parts excellent in a supply paper performance and paper feed performance. SOLUTION: The paper feed roll parts is made of a thermoplastic elastomer and a resin hollow ball A and the thermoplastic elastomer is preferably vinyl chloride base polymer-crosslinking polyurethane thermoplastic elastomer. The resin hollow ball is thermoplastic resin obtained by polymerizing one or more kinds of monomers selected from methyl methacrylate, acrylonitrile, methacrylonitrile, and vinylidene chloride, preferably. The paper feed roll parts has cells composed of the thermoplastic resin.
