A multilayer structure including a metal particles-containing layer, a layer A having a refractive index, n1, and a layer B having a refractive index, n2, and satisfying one of the conditions (1-1) and (2-1) is capable of suppressing reflection of light at a wavelength λ intended to prevent reflection. n1<n2 and λ/4+mλ/2<n1×d1<λ/2+mλ/2  Condition (1-1) n1>n2 and 0+mλ/2<n1×d1<λ/4+mλ/2  Condition (2-1) wherein m represents an integer of 0 or greater; λ represents a wavelength with a unit of nm intended to prevent reflection; n1 represents a refractive index of the layer A; and d1 represents a thickness with a unit of nm of the layer A. |
