PROBLEM TO BE SOLVED: To provide crosslinked amino-resin particles freed from such poor-quality problems as the occurrence of flecks, the occurrence of void, etc. and a method for producing the same. SOLUTION: The method for producing the crosslinked amino-resin particles is so designed to provide favorably such crosslinked amino-resin particles having an average particle diameter of 0.1-20μm and containing coarse particles having a particle diameter of not less than 40μm in a number basis amount of not more than 0.05%.
