Zusammenfassung:	To improve the controllability of filler input and produce moldings with higher performance.SOLUTION: An injection molding apparatus is used to produce a molding body, having a cylinder 11 with a feed port 13h, which is located upstream and from which resin pellets RP are fed, and a feed port 15h, which is located downstream and from which filler F is fed, a screw S deployed therein, and a cutting device 15. The cutting device 15 continuously cuts the thread-like fibers (roving R) to a fixed length and feeds the cut fiber pieces (filler F) into the feed port 15h.SELECTED DRAWING: Figure 1 【課題】フィラーの投入量の制御性を向上させ、より性能の高い成形体を製造する。【解決手段】上流に位置し樹脂ペレットＲＰが供給される供給口１３ｈと、これより下流に位置しフィラーＦが供給される供給口１５ｈとを有するシリンダ１１と、その内に配備されたスクリュＳと、切断装置１５と、を有する、射出成形装置を用いて成形体を製造する。切断装置１５は、糸状の繊維（ロービングＲ）を一定の長さに連続して切断し、切断された繊維片（フィラーＦ）を供給口１５ｈに投入する。【選択図】図１
