Abstract

This adhesive laminated film (50) has a heat-resistant resin layer (10), a flexible resin layer (20), and an adhesive resin layer (30), in the stated order. The peel strength P0 between the heat-resistant resin layer (10) and the flexible resin layer (20) measured by the following method in accordance with JIS Z0237 is from 0.01 N/25 mm to 2.0 N/25 mm, and the peel strength P1 between the heat-resistant resin layer (10) and the flexible resin layer (20) after the adhesive laminated film (50) has been heat treated for four hours at 160°C is from 0.05 N/25 mm to 1.5 N/25 mm. (Method for measuring peel strength) The adhesive laminated film (50) is affixed to a silicon wafer so that the adhesive resin layer (30) is in contact with the silicon wafer. Next, the heat-resistant resin layer (10) is peeled from the flexible resin layer (20) in a 180° direction at a tensile speed of 300 mm/min at 25°C using a tensile tester. The strength (N/25 mm) at that time is measured twice, and the average value is taken as the peel strength.
