Stage: PROBLEM TO BE SOLVED: To provide a semiconductor nanoparticle composite body which can be dispersed in a polar dispersant with high mass fraction while maintaining a high fluorescence quantum efficiency (QY).SOLUTION: A semiconductor nanoparticle composite body according to one embodiment of the invention is a semiconductor nanoparticle composite body in which two or more kinds of ligands including an aliphatic thiol ligand and a polar ligand are coordinated to the surface of a semiconductor nanoparticle. The ligands are composed of an organic group and a coordinating group, and in the aliphatic thiol ligand, the organic group is an aliphatic hydrocarbon group and the coordinating group is a mercapto group, the polar ligand includes a hydrophilic functional group in the organic group, and the hydrophilic functional group includes at least one selected from a hydroxy group, a carboxy group, a carbonyl group, an amino group, an ether bond, an ester bond and a siloxane bond, and the mass ratio of the aliphatic thiol ligand to the polar ligand ((aliphatic thiol ligand)/(polar ligand)) is 0.05-1.00.SELECTED DRAWING: None (Grant)
