A transparent material for shielding undesired electromagnetic waves, in which a black mesh region is formed in a hydrophilic transparent resin layer on a transparent substrate. The present invention thus provides a transparent material for shielding undesired electromagnetic waves, which comprises: n (a) a transparent substrate, n (b) a hydrophilic transparent resin layer formed on the transparent substrate (a), which in certain areas contains metal particles finely dispersed therein to form a black region and in the other area does not contain metal particles, to form a transparent region, and n (c) a metal layer formed on the black region in the hydrophilic transparent resin layer (b); n and a production method therefor. |
