Abstract: A process for producing a high utility wooden synthetic construction material, with a woodgrain appearance close to the texture of natural wood, which effectively uses waste in the form of a wood powder of plywood. A wood powder of plywood, manufactured by adding an adhesive to wood fibers or chips and pressurizing, and a thermoplastic synthetic resin are used as main raw materials. A material obtained by adding an auxiliary raw material to the main raw materials is heated and melted at 160° C. to 200° C., and then pelletized to obtain raw material pellets. The raw material pellets are loaded into an extrusion molding or an injection molding machine, without actively removing contained moisture derived from the wood powder of plywood and an adhesive component from the raw material pellets, heated and melted at 150° C. to 200° C., and extruded from the mold or injected into the mold.
