Abstract
An optical element includes: a base; and an uneven structure layer that is disposed on at least one face of the base, and suppresses reflectance, the optical element having a reflectance of 1% or smaller, in a wavelength region of 400 nm or longer and 700 nm or shorter, a transmittance of 90% or larger, in a wavelength region of 470 nm or longer and 550 nm or shorter, and a variation of transmittance of 1% or smaller, between before and after a high-temperature environmental test conducted at 150° C. for 250 h.
