PROBLEM TO BE SOLVED: To provide a composite material composition having sufficient impact strength while ensuring high stiffness by increasing compounding amount of an inorganic material, and a molded product composed of the composite material composition. SOLUTION: The composite material composition is composed of 50-95 mass% microbody (10) of an inorganic compound such as calcium carbonate, 0.1-30 mass% maleic acid-modified ethylene-butene copolymer rubber and 1-48 mass% polypropylene resin. The molded product is obtained by molding the composite material composition. COPYRIGHT: (C)2009,JPO&INPIT
