Abstract

A structurally colored material (1) includes a substrate (2) and an oxide film (3), which is composed of a metal oxide and which covers the substrate (2). The oxide film (3) includes a porous layer (31), which contains a plurality of pores (311), and which is disposed on the substrate (2), and a dense layer (32), which does not contain pores (311) and which is layered on the porous layer (31). When the thickness of the oxide film (3) is measured at various locations, the thickness of the oxide film (3) at each measurement location is within the range of 150 nm or more and 1000 nm or less and within the range of 0.75 times or more and 1.25 times or less with respect to the mean value of the thickness of the oxide film (3).
