PROBLEM TO BE SOLVED: To produce a large electromagnetic wave shielding material exhibiting excellent electromagnetic wave shielding performance and visibility with high productivity by a printing method. SOLUTION: A mesh pattern of resin composition having an average line width of 50μm or less is formed on a transparent base material by gravure printing method, and a metal layer is provided on that pattern thus producing a transparent electromagnetic wave shielding material imparted with conductivity. High conductivity can be ensured by applying electroless metal plating at the time of forming the metal layer. Thickness of the metal layer can be increased quickly by forming an extra metal layer through electroplating on the metal layer formed by electroless plating. When the metal layer is provided by electroless metal plating, the resin composition being patterned preferably contains a component adsorbing a catalytic metal for electroless metal plating or a catalytic metal becoming the substrate of electroless meta plating. A method for manufacturing the electromagnetic wave shielding material is also provided. COPYRIGHT: (C)2004,JPO
