PROBLEM TO BE SOLVED: To establish both high electromagnetic shielding property and high total ray transmittance by allowing at least the single-surface shape of a transparent macromolecular film to be in a sawtooth shape and coating only one surface out of two surface of a triangular column with metal with improved conductivity. SOLUTION: A transparent polyester film is coated with an acryl UV-curing resin and irradiated with UV rays until a gel shape is attained, a roller is pressed for shaping into a triangular shape, and furthermore it is irradiated with UV rays for complete curing. In this case, an angle formed by a surface where a conductive surface 2 in the two surfaces of the triangular column 1 is not formed and a transparent macromolecular film 3 is preferably equal to 30 degrees or less. Then, the manufactured film is loaded into a vacuum deposition device and is set to that the angle formed by a deposition source and a film normal line is 45-90 degrees, thus depositing aluminum and hence improving total ray transmittance and electromagnetic wave shielding property.
