PROBLEM TO BE SOLVED: To provide a core-shell fine particle that can easily initiate polymerization and gives a cured product exhibiting sufficient mechanical strength, its manufacturing method and a manufacturing method of a fixed colloid crystal. SOLUTION: The core-shell fine particle is constituted of a core fine particle and, covering the outer periphery thereof, a shell layer comprised of a graft chain bearing a photopolymerization-initiating group. The core-shell fine particle has an average particle size of 100-950 nm with a CV value of at most 20% as a percentage of the standard deviation of the average particle size to the average particle size as measured by the dynamic light scattering method. Preferably, the photopolymerization-initiating group is a functional group represented by chemical formula (1). COPYRIGHT: (C)2009,JPO&INPIT
