摘要： The nanocrystal composite (1) according to the present invention comprises a connected aggregate (20) including a plurality of nanocrystal fragments (21) connected to one another, each nanocrystal fragment having a main surface (22) and an end surface (23), and nanoparticles (30) supported on the connected aggregate (20). The plurality of nanocrystal fragments (21) each have a flaky shape; the plurality of nanocrystal fragments (21) have gaps G between the main surfaces (22); and the gaps G are arranged so as to open to the outside of the connected aggregate (20). The nanoparticles (30) have a metallic element different from that of the plurality of nanocrystal fragments (21); and a proportion of a visual field area of the nanoparticles (30) with respect to a visual field area of the plurality of nanocrystal fragments (21) is 2% or more and 50% or less.
