Abstract: The production process of an electromagnetic wave shielding material of the present invention comprises screen printing a conductive paste containing conductive particles, binder and solvent in a geometrical pattern on the surface of a transparent porous layer of a transparent resin substrate provided with the transparent porous layer, the porous layer containing as a main component thereof at least one type selected from the group consisting of an oxide ceramic, a non-oxide ceramic and a metal, followed by forming a conductive portion in a geometrical pattern on the surface of the transparent porous layer by heat treatment. An electromagnetic wave shielding material produced according to this production process has high electromagnetic wave shielding effects and superior transparency and visibility.

Abstract: The primary object of the present invention is to provide a touch panel which has an excellent contact level between a undercoat layer and a substrate on which the undercoat layer is formed. The secondary object of the present invention to provide a touch panel which is lightweight and provided with a wide operating temperature and impact resistance. The primary object is achieved by providing a metal layer between a conductive-layer forming member and an undercoat layer, the metal layer being formed from a single metal element or an alloy of metal elements. The secondary object of the present invention is achieved by using an amorphous polyolefine base resin sheet for forming conductive-layer forming members of the touch and display substrates and using a material for forming a supporting member so that a difference between linear expansion coefficients of the supporting member and each of the conductive-layer forming members is kept within 1×10−5/° C.
