PURPOSE:To enable to unify an appearance without making mechanical strength of a molded article deteriorate, by a method wherein synthetic resin of a master pellet is made identical with that of a natural pellet and flowability of the synthetic resin of the master pellet is made larger than that of the synthetic resin of the natural pellet. CONSTITUTION:Synthetic resin of a master pellet is made identical with that of a natural pellet to improve dispersion of a filler. It is necessary that a ratio of a flowability (a) of the synthetic resin of the master pellet to a flowability (b) of the synthetic resin of the natural pellet if a/b=1.1X1.3. A bundled long fiberlike filler 10 is passed through a die 12 of an extruder 11, the filler 10 is formed 13 by coating the same with the synthetic resin and made into the master pellet by cutting off 14 the same further. Based on the above matter, a surpassing molded article wherein an electrically-conductive filler is dispersed evenly, molding can be performed at a low temperature and low back pressure of a screw, mechanical strength does not deteriorate and appearance is uniform is obtained. |
