    Abstract: An anti-reflection optical member has a laminated structure including: a transparent substrate having a first refractive index greater than that of a predetermined medium; a metal-microparticle-containing layer containing metal microparticles; and a dielectric layer having a second refractive index greater than that of the predetermined medium, in this order. At least 60% of the metal microparticles are flat particles with a diameter-to-thickness ratio of 3 or more. Principal planes of the flat metal particles are surface-oriented in the range from 0° to 30° relative to the surface of the metal-microparticle-containing layer. In the metal-microparticle-containing layer, the metal microparticles are disposed without forming a conductive path. The dielectric layer has such a thickness that light reflected at the surface of the dielectric layer of incident light entering the laminated structure from the surface is interfered and canceled by light reflected at the interface between the dielectric layer and the metal-microparticle-containing layer.

    Abstract: Provided are a bandpass filter having a high light transmittance in a transmission band and a wide wavelength range showing a high transmittance in the transmission band, and a sensor. The bandpass filter is a bandpass filter including a reflective member A and a reflective member B, in which a difference between a reflection center wavelength of the reflective member A and a reflection center wavelength of the reflective member B is larger than a sum of a half width at half maximum of a reflection band of the reflective member A and a half width at half maximum of a reflection band of the reflective member B; the reflective member A has a first cholesteric liquid crystal layer and a second cholesteric liquid crystal layer, and birefringence Δn1 of the first cholesteric liquid crystal layer is larger than birefringence Δn2 of the second cholesteric liquid crystal layer; and the reflective member B has a third cholesteric liquid crystal layer and a fourth cholesteric liquid crystal layer, and birefringence Δn3 of the third cholesteric liquid crystal layer is larger than birefringence Δn4 of the fourth cholesteric liquid crystal layer.
