PROBLEM TO BE SOLVED: To provide a lightweight optical filter having excellent antireflection properties, electromagnetic wave shielding properties, near-infrared shielding properties, durability, and visual clarity. An antireflection layer is formed on one surface of a transparent substrate, an electromagnetic wave shielding layer is formed on the other surface, and a near-infrared shielding adhesive layer is preferably formed on the other surface, preferably leaving an earth electrode extraction portion. To do. [Selection] Figure 3 |
