PURPOSE: An adhesive sheet for electromagnetic interference shielding and a flexible printed circuit board including the same are provided to give reliability to a manufacturing process of the flexible printed circuit board by holding excellent heat resistance, adhesive property, and conductivity. CONSTITUTION: A base material(110) is prepared. A printed circuited pattern layer(120) is formed on the base material. The printed circuited pattern layer comprises a signal circuit(121) and an earthed circuit(122). An electromagnetic wave shielding layer(130) is formed on the printed circuited pattern layer. The electromagnetic wave shielding layer is laminated in order to connect with the earthed circuit. The signal circuit is protected by an insulating layer formed between the printed circuited pattern layer and the electromagnetic wave shielding layer. An electronic device is formed between the insulating layer and the signal circuit. |
