OPTICAL FILTER AND IMAGING DEVICE

The present invention relates to an optical filter which comprises a resin base material containing a resin that has a Tg of 200 DEG C or more, a thickness of 100 [mu]m, 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 DEG C or more relative to the total thickness of resin members is 85% or more. 本发明涉及一种滤光片，所述滤光片具有：树脂基材，所述树脂基材含有树脂，所述树脂的Tg为200℃以上，并且所述树脂在厚度为100μm时满足特定的平均内部透射率和最小内部透射率；规定的介质多层膜；和包含聚酰亚胺树脂和脂环族环氧树脂中的至少一者的外部树脂层，在规定的树脂层中包含最大吸收波长在800nm～1200nm范围内的近红外线吸收色素，并且含有Tg为200℃以上的树脂的构件的厚度相对于树脂构件的合计厚度的比例为85％以上。
