Abstract
Provided is resin molded articles having large elastic modulus, and good appearance. A thermoplastic resin composition contains 80 to 120 parts by weight of a carbon fiber and 0.1 to 3.0 parts by weight of a black colorant, per 100 parts by weight of a (A) crystallizable thermoplastic resin which shows a semicrystallization time (ST (P)) of 20 to 500 seconds, wherein the semicrystallization time is measured by depolarization photometry, under conditions that a sample melting temperature is 20 to 40° C. higher than a melting point of the crystallizable thermoplastic resin, a sample melting time is 3 minutes, and an oil bath temperature for crystallization is 140° C.
