Claim 0:
1. A film-shaped single-layer composite of nanocrystal, characterized in that
the film-shaped single-layer composite of nanocrystal consists of a film-shaped single-layer connected assembly in which a plurality of nanocrystalline pieces each having a flake-shaped form and having a main surface and an end surface are connected to each other,
the main surface of each of the plurality of nanocrystalline pieces exposed to the outside of the connected assembly is arranged so as to form gaps therebetween,
wherein the film-shaped single-layer connected assembly includes a film-shaped connected portion including protruding nanocrystalline pieces from a surface of the film-shaped connected portion, wherein the film-shaped connected portion excluding the protruding nanocrystalline pieces is exposed to the outside of the connected assembly and has a plan view area of 1 mm2 or more,
wherein the plurality of nanocrystalline pieces contain copper oxide; and
when, in a diffraction angle (2θ) of an X-ray diffraction spectrum, a highest peak intensity at 35.0 to 36.0 degrees is taken as I1 and a highest peak intensity at 38.5 to 40.0 degrees is taken as I2, the film-shaped single-layer composite of nanocrystal has a degree of crystal orientation having a peak intensity ratio I1/I2 of 1.05 or more.
