To provide an electromagnetic wave shielding material which comprises a transparent substrate and a fine line pattern formed thereon.
A physical development nuclei layer is preliminarily formed on a transparent substrate; a silver halide emulsion layer is applied thereon; a light-sensitive material having the physical development nuclei layer and the silver halide emulsion layer on the transparent substrate in this order is exposed with an optional fine line pattern; physical development is carried out in an alkali solution in the presence of a soluble silver complex salt-forming agent and a reducing agent; metal silver is precipitated with an optional fine line pattern onto the physical development nuclei layer by physical development; the layer provided on the physical development nuclei layer is removed to expose the physically developed metal silver fine line on the surface; and the metal is electroplated or electroplated as well as electroless plated with the use of the physically developed metal silver fine line as a catalytic nucleus.
