| 1. A method for producing a light-transmitting electromagnetic wave-shielding film having a conductive metal portion and a
light transmitting portion, which comprises
exposing a silver salt-containing layer to an electromagnetic wave, wherein the silver salt-containing layer contains a silver
salt and the silver salt-containing layer is provided on a support,
developing said exposed silver salt-containing layer with a development technique used for a silver salt photographic film
so as to form a metal silver portion, and
subjecting the metal silver portion to physical development and/or plating to form the conductive metal portion consisting
of the metal silver portion carrying conductive metal particles;
wherein the silver salt-containing layer contains Ag and a binder and has an Ag/binder volume ratio of 1/1 or higher.
