Abstract: The present invention relates to an optical filter including a resin base material including an infrared-absorbing pigment layer, and a pair of inorganic dielectric layers which are respectively disposed on or above both main surfaces of the resin base material as outermost layers, in which at least one of the pair of inorganic dielectric layers satisfies at least one of a condition in which a film thickness is 4 μm or greater, and a condition in which the number of layers is 30 or greater, and a ratio of a total film thickness of the pair of inorganic dielectric layers to a film thickness of the resin base material is greater than 8%.
