Zusammenfassung:PROBLEM TO BE SOLVED: To provide means for reducing warp generated in a laminated molding obtained by laminating an in-mold material containing a fiber structure on an injection molding.SOLUTION: An in-mold material containing a fiber structure and used for in-mold molding is used, which is an in-mold material whose area shrinkage ratio is 2% or less, when performing heat treatment for 10 minutes at a higher temperature by 10°C than a resin glass-transition temperature (T) for forming fibers of the fiber structure.SELECTED DRAWING: Figure 1 【課題】繊維構造体を含むインモールド材を射出成形体に積層して得られる積層成形体に発生する反りを低減させる手段を提供する。【解決手段】繊維構造体を含む、インモールド成形に用いられるインモールド材であって、繊維構造体の繊維を形成する樹脂ガラス転移温度（Ｔg）よりも１０℃高い温度で１０分間熱処理したときの面積収縮率が２％以下であるインモールド材を用いる。【選択図】図１
