Insulating Resin Film, Bonded Structure Using Insulating Resin Film, and Production Method of Bonded Structure

摘要

To provide an insulating resin film, which contains: a first adhesive layer, and a second adhesive layer, wherein the insulating resin film is configured to bond a substrate and an electronic part together, and the first adhesive layer is provided at a side of the substrate and the second adhesive layer is provided at a side of the electronic part, wherein the first adhesive layer and the second adhesive layer each contain inorganic filler, wherein the second adhesive layer has a DSC exothermic peak temperature that is higher than a DSC exothermic peak temperature of the first adhesive layer, and wherein a thickness of the first adhesive layer is 50% to 90% of a total thickness of the insulating resin film.
