Abstract:
Provided is a method of producing an electronic device, including a step of preparing a structure which includes an electronic component having a circuit forming surface, and an adhesive laminated film which includes a base material layer, an unevenness-absorptive resin layer, and an adhesive resin layer in this order and in which the adhesive resin layer is attached to the circuit forming surface of the electronic component such that the circuit forming surface is protected; and a step of forming an electromagnetic wave-shielding layer on the electronic component in a state of being attached to the adhesive laminated film.
