Zusammenfassung:	To provide a presheet for appropriately producing a fiber-reinforced thermoplastic excellent in mechanical physical properties, and also to provide a fiber-reinforced thermoplastic excellent in mechanical physical properties.SOLUTION: A pulp fiber-containing presheet at least includes a fine fibrous cellulose-containing layer formed on a pulp fiber-containing layer. In the pulp fiber-containing presheet, the pulp fiber-containing layer contains pulp fibers and a thermoplastic resin, the fine fibrous cellulose-containing layer is an outermost surface layer, a content ratio of a fine fibrous cellulose in a molding thereof is 0.5 mass% or more, and a content ratio of a fine fibrous cellulose in the fine fibrous cellulose-containing layer is 10 mass% or more.SELECTED DRAWING: None 【課題】機械的物性に優れた繊維強化熱可塑性プラスチックを好適に作製するための、プレシートを提供することにある。また、本発明の目的は、機械的物性に優れた繊維強化熱可塑性プラスチックを提供する。【解決手段】少なくともパルプ繊維含有層の上に、微細繊維状セルロース含有層が形成されているパルプ繊維含有プレシートであって、前記パルプ繊維含有層が、パルプ繊維及び熱可塑性樹脂を含み、前記微細繊維状セルロース含有層が最表層であり、前記成形体中の微細繊維状セルロースの含有量割合が０．５質量％以上であり、前記微細繊維状セルロース含有層の中の微細繊維状セルロースの含有量割合が１０質量％以上である、パルプ繊維含有プレシート。【選択図】なし
