PROBLEM TO BE SOLVED: To provide a manufacturing method for molding whose molding powder can be given functional properties such as heat resistance and strength anew as an issue to be solved in the manufacturing method for the molding using lignin powder. SOLUTION: The resin molding with a multifunction of high strength, high heat resistance and the like is obtained by kneading the molding powder with an acrylic resin liquid containing uniformly dispersed ultrafine grains of 10 nm class such as SiO2 or Al2O3 and molding/hardening the mixture.
