Abstract
A metal film 21 is laminated directly to or by means of an adhesive 13 to a transparent base sheet 11. A mesh metal film including lines defining apertures is formed by coating the metal film 21 with a mesh resist layer 109a patterned in a mesh, etching the metal film 21 through the mesh resist layer 109a, and removing the mesh resist layer 109a. The front surfaces and side surfaces of the lines of the mesh metal film are coated with a black coating layer 23.
