(57) [Summary] [Purpose] To realize a composite material injection-molded article which is lightweight and has good electrical characteristics such as conductivity, and a method for producing the same. [Structure] A hopper 9 is charged with a composite material 13 in which granules of a metal or an alloy thereof having a low melting point, thermoplastic pellets, and additives are preblended in advance.
The composite material 13 in the hopper 9 is introduced into the cylinder barrel 2 heated by the heater 14 by a predetermined amount by the feeder 10, and is kneaded and melted while being conveyed forward by the rotating screw 1. The melted metal or alloy has a lower viscosity and a larger interfacial energy than the melted thermoplastic and thus exhibits a matrix structure, in which the thermoplastic is dispersed in a granular or dendritic form. Next, the molten composite material is injected and filled into the cavity 5A of the mold 5 that is clamped by the mold clamping device 15.
