To provide a method for manufacturing a resin composite granule, which can more reduce the variation in the binding amount of a particulate additive per one piece of resin pellets than conventionally, and a method for manufacturing a resin molded article using a resin composite granule manufactured by the method.

The method for manufacturing a resin composite granule includes mixing an additive dispersed liquid in which a resin pellet and a particulate additive are dispersed in a dispersion medium while an adhesive is added and the liquid component is removed to bind the particulate additive on the resin pellet surface with the adhesive. According to this method, the variation in the binding amount of a particulate additive per one piece of resin pellets can be more reduced than heretofore.
