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, a near infrared shielding layer is formed on the other surface, an electromagnetic wave shielding layer is formed thereon, and an adhesive layer is formed thereon. Preferably, a part of the electromagnetic wave shielding layer is left exposed to be used as a ground electrode extraction part. [Selection] Figure 3 |
