PROBLEM TO BE SOLVED: To improve color reproducibility in a red area and to miniaturize a device.SOLUTION: A plurality of lenses or lens components and an optical element are arranged on an optical path, and the optical element comprises a substrate formed of a film-like resin material having an infrared absorption function and a multilayer film formed on both a surface on the object side and a surface on the image side of the substrate and adjusts spectral characteristics. A spectral transmittance of the optical element and spectral reflectances of the surface on the object side and the surface on the image side satisfy a prescribed conditional expression. |
