It is possible to prevent the generation of bubbles even when heated and deformed after being bonded to a substrate, and has a followability to deformation of the substrate when a laminate of a substrate / adhesive resin layer / substrate is formed. A good adhesive resin layer and an adhesive resin film are provided. A single-layer adhesive resin layer 11 made of an acrylic adhesive resin composition, the adhesive resin composition comprising at least (A) an acrylic polymer and (B) an acrylic monomer or acrylic. -Based oligomer and (C) thermal polymerization initiator, the adhesive resin layer 11 has adhesiveness to both surfaces 11a and 11b at room temperature, and differential scanning calorimetry (DSC) at a heating rate of 10 ° C / min. ), Heat generation begins to be confirmed at 80 ° C. or higher, and at least one peak is confirmed between 120 ° C. and 210 ° C.
