PROBLEM TO BE SOLVED: To provide a method for selectively forming a black matrix on a surface of a fine metal conduction with high dimensional precision, and for inexpensively and easily manufacturing an electromagnetic wave shielding film superior in electromagnetic wave shielding property and optical transparency. SOLUTION: The manufacturing method of the electromagnetic wave shielding film comprises processes of: forming a transparent substrate resin film 1 by a fusion extrusion molding method; forming a transparent substrate 1 having a mesh-like recess 3 by pressing a cooling roll 2 where a mesh-like projection is disposed on the surface of the resin film 1; forming the metal conduction part 4 in the recess 3; and forming the black matrix part 5 by applying liquid composite comprising carbon particulate having a polar group, hydrophilic polymer and water on the metal conduction part 4 and removing water.
