Zusammenfassung:	The present invention improves the controllability of a filler injection amount and produces a molded article exhibiting higher performance. In the present invention, an injection molding device is used to produce a molded article, the injection molding device having: a cylinder 11 having a supply port 13h which is located upstream and into which resin pellets RP are supplied and a supply port 15h which is located downstream thereof and into which a filler F is supplied; a screw S disposed inside the cylinder 11; and a cutting device 15. The cutting device 15 continuously cuts a thread-like fiber (roving R) into a fixed length and injects the cut fiber pieces (filler F) into the supply port 15h.
