PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition for injection molding, not requiring the production of a new mold because of hardly causing warp deformation which is the molding defect of a molded product and hardly reducing mold-releasability, even if the molding is carried out by using a conventional mold for molding a polyolefin-based resin when the content of a woody material in the resin composition for injection molding is high. SOLUTION: The thermoplastic resin composition for injection molding comprises (A) a polystyrene-based resin, (B) a polyolefin-based resin and (C) the woody material. The content of the woody material (C) in the composition is 20-70 wt.%, and the ratio of the polystyrene-based resin (A) to the polyolefin- based resin (B) is (95-40):(5-60) by weight.
