PROBLEM TO BE SOLVED: To provide a fine particle structure body for preventing aggregation, a light-emitting device using it, and a method for manufacturing the fine particle structure body. SOLUTION: A fine particle structure body is provided with a plurality of fine particles 11, made of ZnO or the like, and each of the fine particles 11 is connected to one another in a network form by a crosslinking part 12. More specifically, the crosslinking part 12 that exists among particles becomes a support part, thus preventing the fine particles 11 from being aggregated. Each of the fine particles 11 is composed of a fine crystal with a crystal particle diameter of 100 nm or less and has an inter-band luminous function and a donor acceptor pair luminous function. This sort of fine particle structure body is used as a material for composing the luminous part of a light-emitting device. The fine particle structure body is manufactured by applying a voltage between positive and negative electrodes with pure water as an electrolyte, a highly pure Zn plate as the positive electrode, and a semiconductor substrate as the negative electrode.
