PURPOSE: An electromagnetic interference filter is provided to reduce manufacturing procedures and costs by eliminating the necessity of manufacturing a near infrared ray shield film and laminating the film to the electromagnetic interference filter. CONSTITUTION: An electromagnetic interference filter(300) comprises a transparent base(310); a conductive metal sheet(320) formed into the thickness of 3 to 100§ on the transparent base, and which has a mesh(321) formed by an etching process, and a blackening film(323) formed into the thickness of 1 to 2§ at one of the upper and lower surfaces of the conductive metal sheet so as to prevent a reflection; and a near infrared ray shield layer(330) made of a mixture of a shielding material of 0.01 to 20 weight% and a transparent resin of 80 to 99.99 weight% for flattening the surface of the metal sheet where the mesh is formed. The near infrared ray shield layer is formed on the metal sheet. |
