PROBLEM TO BE SOLVED: An optical filter in which the near-infrared shielding property is lowered even when used for a long time, a specific absorption appears in the visible region, and a problem such as coloring or discoloration is solved, and particularly excellent in light resistance. An optical filter is provided. An optical filter 1 comprising at least a transparent substrate 2, a near-infrared absorbing layer 3 containing a near-infrared absorbing dye that absorbs near-infrared rays in a transparent binder resin, and an ultraviolet absorbing layer 4, which is below 380 nm. The ultraviolet absorbing layer 4 is provided so that the optical filter has a light transmittance of 30% or less at all wavelengths in the region. [Selection] Figure 1 |
