description	Provided is a method for manufacturing a molded body that has superior transparency, processability, and formability while still suppressing the occurrence of coloring. A method for manufacturing a molded body (10) has a film-material forming step (33) and a molding step (32). In the film-material forming step (33), an elongated film material is formed from cellulose acylate. In the molding step (32), the obtained film material (20) and a substrate material (22) formed of a thermoplastic resin are integrally molded thereby forming the molded body (10) having a cellulose acylate film (13) and a transparent substrate (11) by thermoforming at a forming temperature in the range of 150-240°C inclusive. La présente invention concerne un procédé de fabrication d'un corps moulé qui présente une transparence, une aptitude au traitement et une formabilité supérieures tout en supprimant toujours l'apparition de coloration. Un procédé de fabrication d'un corps moulé (10) comprend une étape de formation de matériau de film (33) et une étape de moulage (32). Dans l'étape de formation de matériau de film (33), un matériau de film allongé est formé à partir d'acylate de cellulose. Dans l'étape de moulage (32), le matériau de film obtenu (20) et un matériau de substrat (22) composé d'une résine thermoplastique sont moulés d'un seul tenant, formant ainsi le corps moulé (10) ayant un film d'acylate de cellulose (13) et un substrat transparent (11) par thermoformage à une température de formation dans la plage de 150 à 240 °C inclus. 着色の発生を抑制し、かつ透明性と加工性と成形性とにより優れた成形体の製造方法を提供する。　成形体（１０）の製造方法は、フィルム材形成工程（３３）と成形工程（３２）とを有する。フィルム材形成工程（３３）は、セルロースアシレートから長尺のフィルム材を形成する。成形工程（３２）は、得られたフィルム材（２０）と、熱可塑性樹脂から形成された基材用素材（２２）とを、１５０℃以上２４０℃以下の範囲内の成形温度の熱成形で一体成形することにより、セルロースアシレートフィルム（１３）と透明な基材（１１）とを有する成形体（１０）にする。
