Title:
電磁波シールドシート
Document Type and Number:
Japanese Patent JP5722775
Kind Code:
B2
Abstract:
Disclosed is an electromagnetic shielding sheet that has a smaller increase in the thickness of a base after the formation of a metal coating film when compared with conventional electromagnetic shielding sheets, and which has excellent electromagnetic wave shielding properties despite a small amount of adhered metal. According to the present invention, the electromagnetic shielding sheet can endure metal working processes and has high electromagnetic wave shielding properties, resulting in a thin, very flexible fabric sheet. Specifically disclosed is an electromagnetic shielding sheet which is composed of a laminated non-woven fabric that has at least a first layer and a second layer, and which is characterized in that the first layer is a layer of thermoplastic synthetic fibers having a fiber diameter of 6 µm to 50 µm, the second layer is a layer of ultrafine fibers having a fiber diameter of 0.1 µm to 5.0 µm, and a metal is adhered to at least one surface of the sheet.
