PROBLEM TO BE SOLVED: To provide a transparent adhesive film which is used for bonding a display device of a touch panel and a position input device thereof together or for bonding a surface protective cover and the touch panel together, and which is excellent in adhesion reliability and reworkability.SOLUTION: A transparent adhesive film is used for bonding a display device of a touch panel and a position input device thereof together or for bonding a surface protective cover and the touch panel together, and contains an adhesive component and a gas generating agent to generate gas by irradiation of ultraviolet light of 320 nm or lower. In the transparent adhesive film, the gas generating agent has a weight absorption coefficient of 10abs or less at a wavelength of 365 nm, a weight absorption coefficient of 10abs or more at a wavelength of 320 nm, and a 5% heating loss temperature of 250°C or more when temperature is raised to 400°C at a rate of 5°C/min in air.SELECTED DRAWING: None |
