Abstract
The present invention is to provide an electromagnetic wave shielding material including a transparent substrate and a convex pattern layer composed of a conductive composition formed in a prescribed pattern on the transparent substrate, wherein the conductive composition contains conductive particles and a binder resin; and in observation of a transverse cross section of the convex pattern layer by electron microscopic photography, at least a part of the conductive particles has a fused continuation and a method for manufacturing the same. The electromagnetic wave shielding material and the method for manufacturing the same include a configuration capable of achieving a lower surface resistivity in an electromagnetic wave shielding material which is required to achieve a much more reduction in a line width of the pattern, specifically, a reduction to a line width of not more than 30 μm, and more preferably not more than 15 to 20 μm and a treatment method capable of reducing the surface resistivity by an easy and short-time treatment.
