PROBLEM TO BE SOLVED: To provide a method for efficiently producing a chitin-chitosan film having cell affinity and bone conductivity, and in which calcium phosphate is precipitated on one side of a base material film as a scaffold material for bone cell propagation having strength.SOLUTION: Provided is a method for producing a scaffold material for bone cell propagation comprising: a step where chitin-chitosan films are piled each other and adhered to obtain an adhesive film a step where calcium phosphate is produced on both the sides of the adhesive film and a step where the adhesive film is separated into the chitin-chitosan films each other. By the production method, a chitin-chitosan film in which calcium phosphate is precipitated only on one side of calcium phosphate can be easily produced.COPYRIGHT: (C)2016,JPO&INPIT【課題】細胞親和性および骨伝導性を有し、また強度ももった骨細胞増殖用足場材料として、基材膜の片面にリン酸カルシウムを析出させたキチン・キトサン膜を効率よく製造する方法が嘱望されている。【解決手段】キチン・キトサン膜同士を重ね合わせて密着させ密着膜を得る工程と、前記密着膜の両面にリン酸カルシウムを生成する工程と、前記密着膜を前記キチン・キトサン膜同士に分ける工程を含むことを特徴とする骨細胞増殖用足場材料の製造方法によって、リン酸カルシウムを片面だけに析出させたキチン・キトサン膜が容易に作製することができる。【選択図】図2
