Abstract

The present invention relates to an adhesive film including a photothermal conversion layer including a light absorber and a thermally decomposable resin; and an adhesive layer, in which the thermally decomposable resin has a —COOH or —OH functional group and includes two kinds of acrylic resins having different weight average molecular weights, and an adhesive substrate including the adhesive film and a substrate to be processed. In the adhesive film and the adhesive substrate according to the present invention, it is possible to simplify a processing process of the substrate and reduce costs and time, and prevent damage to a substrate and a circuit or an element formed on the substrate.
