Abstract
The present invention provides a film application method that can prevent entry of foreign substances and air bubbles between the film and the application target even when the film is applied in a general environment in which foreign substances such as dust are floating. The film application method is a film application method that applies a functional film to a substrate, the method including the steps of: (1) applying a first adhesive layer to the substrate, with a foreign-substance-removing unit including the first adhesive layer and a first film being overlaid onto a main unit including a second film, a second adhesive layer, and the functional film; and (2) while peeling off both the foreign-substance-removing unit and the second film, with one end of the functional film fixed to the substrate, by pulling ends of the foreign-substance-removing unit and the second film adjacent to the fixed end of the functional film through between the substrate and the functional film, applying the second adhesive layer exposed by removal of the second film to the surface of the substrate exposed by removal of the foreign-substance-removing unit.
