The present invention provides a layered film that adheres sufficiently well to a coating layer such as a hard coating layer, and oligomer separation from the coating layer is suppressed during heat treatment. The present invention pertains to a layered film having a polyester resin layer on at least one surface of a polyester film substrate, wherein 5 to 70% (molar) of a diol component of the polyester resin constituting the polyester resin layer is a diol component having a tricyclodecane structure, and the degree of change in haze when the film is heat treated for one hour at 150°C is 1.0% or less. |
