In a functional composite film in which the outermost surface formed by laminating an organic layer and an inorganic layer is an organic layer, the adhesion between the organic layer and the inorganic layer is high, and when a quantum dot layer or the like is laminated In addition, a functional composite film capable of obtaining high adhesion and a quantum dot film using the functional composite film are provided. SOLUTION: One or more combinations of an inorganic layer and a base organic layer are included, the outermost surface is an organic layer, the outermost organic layer has a urethane polymer main chain and a terminal (meth) acryloyl group side chain. , A UV-curable urethane polymer having a weight average molecular weight of 5000 to 30000 and a double bond equivalent of 300 g / mol or more, a curable urethane polyester, a phosphoric acid compound containing 2 or less (meth) acryloyl groups and one (meth) This problem is solved by using at least one of the silane coupling agents containing an acryloyl group.
