<p>An optical body includes a first optical layer (4) having a concave-convex surface, a wavelength-selective reflecting layer (3) formed on the concave-convex surface, and a second optical layer (5) formed on the wavelength-selective reflecting layer to embed the concave-convex surface, the wavelength-selective reflecting layer having a multilayer structure formed by successively stacking at least a first high refractive index layer, a metal layer, and a second high refractive index layer, wherein, given that optical film thicknesses of the first high refractive index layer and the second high refractive index layer are x and y, respectively, and a geometrical film thickness of the metal layer is z, x, y and z satisfy the following formula (1):</p> |
