Abstract

Provided is an antireflective member capable of improving scratch resistance. An antireflective member having a low refractive index layer on an optically transmissive substrate, the low refractive index layer containing a binder resin and hollow particles, wherein the antireflective member satisfies the following condition 1. <condition 1> In a region of 5 μm×5 μm on a surface of the antireflective member on a side having the low refractive index layer with respect to the optically transmissive substrate, spatial frequency analysis of elevation is performed to calculate power spectrum intensity of elevation for each wavelength; when a sum of power spectrum intensity of elevation for each wavelength is calculated and the sum is normalized to 1, the power spectrum intensity P1 of elevation at a wavelength of 1.25 μm is 0.015 or more.
