Abstract
A general-purpose electromagnetic wave shielding interior material having an excellent electromagnetic wave shielding property as well as a good interior finishing property is disclosed. A protective film made of resin is stuck onto one side surface of an electromagnetic wave shielding metal foil, and an incombustible paper sheet is stuck onto the other side surface of the same electromagnetic wave shielding foil to form a laminated sheet having the desired properties. Preferably, the electromagnetic wave shielding metal foil is exposed from the peripheral edge portion of the laminated sheet, and an overlapping margin is reserved at the peripheral edge portion of the laminated sheet.
