Zusammenfassung:	To provide a laminate having no wrinkle caused by a peripheral length difference between the inside and the outside while using a tape of a wide width, in order to enhance productivity, and a production method thereof.SOLUTION: A production method of a laminate using a unidirectional prepreg substrate includes at least (a) a transformation step for transforming a unidirectional prepreg substrate having a partial notch cut by cutting means, (b) a lamination step for laminating the unidirectional prepreg substrate, (c) a cutting step for cutting the unidirectional prepreg substrate to a necessary length, and (d) a lamination repeating step for repeating the steps (b), (c).SELECTED DRAWING: Figure 1 【課題】生産性を向上させるために、太幅のテープを用いつつ、内側と外側の周長差を起因とするシワを生じさせない積層体およびその製造方法を提供する。【解決手段】一方向プリプレグ基材を用いた積層体の製造方法であって、少なくとも（ａ）切込手段により部分的な切込を設けられた一方向プリプレグ基材を変形させる変形工程、（ｂ）前記一方向プリプレグ基材を積層する積層工程、（ｃ）必要な長さごとに前記一方向プリプレグ基材をカットするカット工程、（ｄ）（ｂ）、（ｃ）工程を繰り返す繰り返し積層工程、からなることを特徴とする積層体の製造方法。【選択図】図１
