Abstract (en)
A minute structure has at least one of optical functions including a reflection/interference function to visible light ray, a reflection function to infrared ray and a reflection function to ultraviolet ray. The minute structure comprises a plurality of first and second polymer layers which are alternately put on one another in the direction of the thickness to constitute a layer unit, each first polymer layer having an optical refractive index "na" and a thickness "da", and each second polymer layer having an optical refractive index "nb" and a thickness "db". The minute structure is formed to satisfy the following condition: under the conditions of "1.3 ≤ na" and "1.01 ≤ nb/na ≤ 1.40", the peak wavelength " lambda 1" of primary reflection satisfies the following formula: <MATH> the ratio "nb.db/na.da" of the optical thickness "nb.db" of the second polymer layer to that "na.da" of the first polymer layer satisfies the following formula: <MATH> <IMAGE>
