Abstract
An antireflection member comprising an antireflection layer includes two adjacent layers with different refractive indices, the antireflection layer formed at least on a first surface of a support substrate, and one of the two adjacent layers with different refractive indices located farther from the support substrate is a first layer, and another of the two adjacent layers is a second layer, wherein the antireflection layer contains two or more kinds of particles of different constituent elements and one or more kinds of binders, and a ratio b/a is more than 1.10 and less than 1.45, where 'a' denotes a length of the line segment A1A2 connecting two arbitrarily-selected points A1 and A2 located on an interface between said first layer and said second layer and apart from each other by a linear distance of 500 nm or more, and 'b' denotes a length of a line formed by projecting the line segment A1A2 in a direction perpendicular to the first surface of the support substrate onto the interface between the first layer and the second layer.
