PROBLEM TO BE SOLVED: To eliminate print missing or unevenness when a resist pattern is formed on a conductive metal foil by printing in order to enable a light transmissive electromagnetic wave shielding sheet to be manufactured as a scroll of a continuous band state in a large area to be applicable to a window, etc. SOLUTION: When the light transmissive electromagnetic wave shielding sheet 10 is manufactured by laminating a transparent base material 1 of polyethylene terephthalate, etc. and a conductive metal foil 2A of a copper foil, etc. via an adhesive 3, then providing a resist pattern on the surface of the conductive metal by a flexography and etching the metal foil to a pattern metal layer 2, a surface roughness of the print surface fa of the metal foil is set to 1.0-3.0μm by an arithmetic mean roughness Ra according to JIS B 0601.
