ABSTRACT:
The invention relates to a minute structure for showing an interference color having a certain wavelength within a visible light region, by reflection and interference of a natural light incident on the minute structure. The minute structure has: a laminated portion including a plurality of first layers having a first refractive index and a plurality of second layers having a second refractive index different from the first refractive index; and a stray-light absorbing member. The first and second layers are alternately placed on top of each other. The stray light has wavelengths other than the certain wavelength and is formed by transmittance of the natural light through the laminated portion, reflectance of the natural light by the laminated portion and/or scattering of the natural light by the laminated portion. The invention further relates to a fabric for showing the interference color. The fabric includes: a first thread which is one of a warp and a weft; and a second thread which is the other of the warp and the weft. The first and second threads are woven to form the fabric. The first thread is made of a material containing the laminated portion. The second thread is made of a material containing the stray-light absorbing member. By the provision of the stray-light absorbing member, the interference color becomes brighter and deeper and higher in value.
