The present invention relates to an optical filter which comprises a resin base material containing a resin that has a Tg of 200°C or more, a thickness of 100 μm, a specific average internal transmittance and a specific minimum internal transmittance, a specific dielectric multilayer film, and an external resin layer containing at least one of a polyimide resin and an alicyclic epoxy resin, wherein: a near-infrared absorbing dye having a maximum absorption wavelength of 800-1,200 nm is contained in a specific resin layer; and the ratio of a member that contains a resin having a Tg of 200°C or more relative to the total thickness of resin members is 85% or more. |
