PROBLEM TO BE SOLVED: To produce a thermoplastic resin molding continuously by extruding a thermoplastic resin composition containing a thermoplastic resin and a filler. SOLUTION: With the use of an extruder 1 in which an auxiliary raw material charging port 7 is formed downstream from a main raw material charging port 4, and one or more vent holes 8, 9 are formed on the upstream side and downstream side of the port 7, respectively, a thermoplastic resin is charged from the port 4 and a filler is charged from the port 7, the mixture, while being kneaded/melted, is deaerated from the vent holes 8, 9, and a thermoplastic resin molding S is extruded, while being solidified, from a shaping mold 5 fitted at the tip of the extruder 1 and a cooling mold 6 connected with the mold 5.
