    Abstract: An adhesive film includes an adhesive layer containing an adhesive; and a release film disposed on at least one surface of the adhesive layer, temperature dependence of a relative dielectric constant of the adhesive layer that is determined by a test for evaluating temperature dependence is equal to or less than 30%, and the adhesive contains an acryl-based adhesive. The adhesive film including the adhesive layer can inhibit the occurrence of malfunctioning of a capacitance-type touch panel in an environment of a wide temperature range from a low temperature to a high temperature.
