PURPOSE: A manufacturing method of transparent flexible film is provided to form an inorganic layer on the surface of a transparent substrate film, thereby capable of manufacturing a flexible transparent film with excellent mechanical flexibility even with low moisture permeability and oxygen permeability. CONSTITUTION: A manufacturing method of transparent flexible film comprises: a step of ionized metal compound on the surface of a transparent substrate film and forming a first inorganic layer(110) by conducting natural curing in order to react with moisture in air; and a step of coating an organic layer on the first inorganic layer; and additionally, a step of coating ionized metal compound on the surface of the organic layer, and forming a second inorganic layer(130) through natural curing in order to react with moisture in air.
