PROBLEM TO BE SOLVED: To provide a manufacturing method of a nanoparticle dispersion body wherein coagulated powder of nanoparticles is wet-crushed in a short time into nanoparticles with an average particle size of 100 nm or less, in particular, 50 nm or less. SOLUTION: The manufacturing method of the nanoparticle dispersion body of manufacturing the nanoparticle dispersion body from the coagulated powder of nanoparticles using a wet crusher using beads, includes wet-crushing processes of n-kinds with different average particle sizes of the beads, n being an integer of 2 or higher. The average particle size of the beads in the [k-1]th, (2≤k≤n), is larger than the average particle size of the beads used in a k-th process. COPYRIGHT: (C)2010,JPO&INPIT
