PROBLEM TO BE SOLVED: To prevent the occurrence of the aggregation of adding materials at a weld part or at the part where the turbulent flow of resins occurs in a forming mold and to homogeneously disperse the adding materials and improve the impact resistance of molded materials in which adding materials such as aluminum, carbon fiber and the like are mixed for the purpose of ornament. SOLUTION: The adding material 12 such as aluminum, the carbon fiber and the like used in the field of the ornament is added to the resin material 11 such as PP resins, talc-containing PP resins and the like, and a compatibilizing agent such as maleic acid which improves wetability (firm adhesion) is added. By this, the resin material 11 and the adding materials 12 are homogeneously dispersed in the mold, and accordingly the occurrence of a faulty external appearance such as aggregation and so on is prevented, a good external appearance is secured, the aggregation of the adding material inside a screw is prevented and the maintenance of an injection machine is simplified. Further, the formation of space 13 between the resin material 11 and the adding material 12 is prevented by the addition of the compatibilizing agent, and the impact resistance is improved by preventing the formation of cracks, and the amount of the adding material 12 is possibly increased.
