PROBLEM TO BE SOLVED: To provide a production method for a fiber reinforced resin material which is capable of suppressing a fibrous material group from moving when a resin is injected, and thereby prevents physical property and appearance quality thereof from being degraded.SOLUTION: The present invention is a production method for a fiber reinforced resin material, comprising: a first step of fixing a fibrous material group which is composed of cut fibrous materials F1', F2' on a film FL or in a mold K; and a second step of providing a softened resin onto the film FL or into the mold K and applying pressure and heat to produce the fiber reinforced resin material M1. The first step includes: a method of fixing the fibrous material group by adhering the fibrous material group on a surface of a sheet S impregnated with a resin; or a method of fixing the fibrous material group disposed on the film FL or in the mold K with a holding plate Bo1 with holes H through which the resin is provided, and providing the resin through the holes H to the fibrous material group. 【課題】樹脂を注入した際に繊維材群が動くのを抑制でき、もって物性や外観品質が低下することのない繊維強化樹脂材の製造方法を提供する。【解決手段】裁断された繊維材Ｆ１'、Ｆ２'からなる繊維材群をフィルムＦＬ上もしくは成形型Ｋ内で固定する第１のステップ、フィルムＦＬ上もしくは成形型Ｋ内に軟化した樹脂を提供し、加圧と加熱を実施して繊維強化樹脂材Ｍ１を製造する第２のステップからなる繊維強化樹脂材の製造方法である。第１のステップにおいては、樹脂が含浸されたシートＳの表面に繊維材群を付着させて繊維材群を固定する方法や、樹脂が提供される孔Ｈを備えた押さえ板Ｂｏ１でフィルムＦＬ上もしくは成形型Ｋ内に配設された繊維材群を固定し、孔Ｈを介して樹脂が繊維材群に提供される方法などがある。【選択図】図１
