Zusammenfassung:	The present invention provides a laminated film which includes a pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer, and a die-adhering layer laminated on the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet, in which the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet is formed of a pressure-sensitive adhesive composition containing a base polymer and a thermal crosslinking agent, and the pressure-sensitive adhesive layer is such that the gel fraction thereof before heating is less than 90% by weight and the gel fraction thereof after heating is changed to 90% by weight or more.
