rate of 100 sec 1 of 5 000 to 40 000 are preferred a composition comprising 50 by weight or more of the above described vinylidene fluoride resin and other thermoplastic resin can also be used as the vinylidene fluoride resin according to the present invention the vinylidene fluoride resin can be used in an amount of 30 to 92 by weight based on the weight of the composition the carbon fiber which can be used in the present invention can be the commercially available carbon fibers the carbon fibers having a length of 5 mm or more are particularly preferred from the standpoints of the effect of the present invention and the tensile strength the amount of the carbon fiber is from 3 to 10 by weight preferably from 5 to 10 by weight based on the weight of the composition if the amount of the carbon fiber is less than 3 by weight the mechanical strength of the molded article is insufficient and if the amount thereof is more than 10 by weight it is difficult to suppress the formation of warpage on the surface of the molded article the graphite which can be used in the present invention is the granular graphite wherein 20 by weight or more preferably 30 by weight and most preferably 50 by weight of the granular graphite has.
