Abstract
Disclosed is a transparent electromagnetic wave shielding material comprising a black electroconductive synthetic fiber gauze embedded in a molded synthetic resin body composed of diethylene glycol bisallyl carbonate. This gauze is preferentially located in the vicinity of the surface of the molded body, and the resin surface sinks in the portions of mesh openings of the gauze to impart a light scattering property to the surface.
