An optical filter includes a glass substrate in which an average-optical-transmittance in a specific-visible-region defined as a wavelength range of 430 nm to 650 nm is 80% or more and an average-optical-transmittance in a specific-infrared-region defined as a wavelength range of 900 nm to 1,000 nm is 25% to 85%, a first-optical-multilayer film in which an average-optical-transmittance in the specific-visible-region is 80% or more and an average-optical-transmittance in the specific-infrared-region is in a range of 45% to 65%, the first-optical-multilayer film having, between the specific-visible region and the specific-infrared-region, a first-blocking-band that blocks light, and a second-optical-multilayer-film in which an average-optical-transmittance in the specific-visible-region is 80% or more and an average-optical-transmittance in the specific-infrared-region is in a range of 45% to 65%, the second-optical-multilayer film having, on a side of wavelengths longer than those in the specific-infrared-region, a second-blocking-band that blocks light.
