<P>PROBLEM TO BE SOLVED: To provide a thermoplastic composite material capable of giving molded articles having small coefficients of linear expansion, and to provide a molded article using the same. <P>SOLUTION: The thermoplastic composite material is characterized by comprising fine inorganic particles surface-modified with at least hexadecyl group-having functional groups and polymethyl methacrylate, wherein the content of the fine inorganic particles is ≥30 and ≤80 vol.%. The molded article prepared by molding the thermoplastic composite material is characterized in that the coefficient of linear expansion of the molded article in a range of 20-60°C is ≤20×10<SP POS="POST">-6</SP>/°C (including negative coefficients of linear expansion). <P>COPYRIGHT: (C)2013,JPO&INPIT |
