To provide a method of manufacturing an electromagnetic wave shield sheet that has a low haze value and is superior in visibility enough to clearly recognize an image on a display.

The method of manufacturing the electromagnetic wave shield sheet 10 includes: forming a plurality of openings and a line portion surrounding and sectioning them by removing parts of a metal foil having an uneven surface by etching after sticking the uneven surface side of the metal foil on a transparent base with an adhesive layer interposed and transferring the uneven surface to the adhesive layer; and then forming a flattening layer which covers the openings and line portion and substantially does not contains an air layer on an interface with the adhesive layer exposed from the openings. In this case, the line portion and openings are coated with a liquid ionization radiation curing type resin composition to form a coating, which is cured by irradiation with ionization radiation to form the flattening layer.
