PROBLEM TO BE SOLVED: To provide an optical filter with an electromagnetic wave shield having a high antireflection effect and strong electromagnetic wave shieldability. SOLUTION: A transparent substrate 1 and the front surface of metallic pattern layers 2 formed atop the transparent substrate are provided with a planarization layer 3 to planarize the ruggedness of the metallic pattern layers and the transparent substrate and thereafter, an antireflection layer 4 is formed thereon, by which the coating unevenness resulted when an antireflection agent is directly applied on the metallic pattern layers and the air bubbles generated when an antireflection film is stuck thereon may be prevented and the antireflection effect may be improved. A metal oxide having a high refractive index is incorporated into a planarizing agent for forming the planarization layer 4, by which the improvement in the antireflection effect by a combination with the antireflection layer of the low refractive index is made possible. |
