PROBLEM TO BE SOLVED: To provide a core-shell type spherical composite cured melamine resin particle whose shell layer thickness is larger than those of conventional particles to improve the light-scattering characteristic and light-reflecting characteristic of the particle for visible light, and further to provide a method for producing the resin particle. SOLUTION: This core-shell type spherical composite cured melamine resin particle whose core comprises a melamine-based resin, whose shell comprises a melamine-based resin-silica composite layer tightly filled with colloidal silica having an average particle diameter of 5 to 70 nm, and which has a shell layer thickness of 80 to 400 nm, and its production method.
