Optical body, manufacturing method of optical body, laminate, and image sensor

Abstract

An optical body that has excellent anti-reflection performance and transmittance for light having wavelengths in the visible light band and good absorption performance for light having wavelengths in the near-infrared band is provided. To solve the above problem, the present disclosure provides an optical body 100 including a base material 20, a dye-containing resin layer 30 formed on the base material 20, and an anti-reflection layer 40 formed on the resin layer 30 and having a micro uneven structure in at least one surface. The average spectral transmittance of the optical body 100 for light in a wavelength range of 420 to 680 nm is 60% or greater, and the minimum spectral transmittance of the optical body 100 for light in a wavelength range of 750 to 1400 nm is less than 60%.
