PROBLEM TO BE SOLVED: To provide an adhesive film which suppresses precipitation of an oligomer in an adhesive layer or on a film surface, for instance, when exposed to high temperatures and is hardly peeled from a polyester film having an adhesive layer acting as a substrate.SOLUTION: There is provided an adhesive film in which an undercoat layer and an adhesive layer are sequentially provided at least one surface of a polyester film, and the undercoat layer is a coating liquid containing a crosslinking agent and a polymer other than the crosslinking agent. The adhesive film is a coating layer that is formed of a coating liquid in which a content of the polymer in the coating liquid is 30 wt.% or less as a ratio of a nonvolatile component.SELECTED DRAWING: None |
