Optical filter

An optical filter, comprising:

• a substrate,
• a dielectric multilayer film 1 laid on or above one major surface of the substrate, and
• a dielectric multilayer film 2 laid on or above the other major surface of the substrate,
• wherein
• the substrate comprises a near infrared ray absorbing glass and a resin film,
• the resin film has a thickness of 10 μm or less,
• the resin film comprises a resin and a pigment (NIR1), and
• the optical filter satisfies all of the following spectral characteristics (i-1) to (i-3), and (i-6) to (i-8):
• (i-1) in a spectral transmittance curve at an incident angle of 0 degrees, an average transmittance T450-600(0deg)AVE at a wavelength of 450 nm to 600 nm is 80% or more,
