PROBLEM TO BE SOLVED: To obtain a cosmetic giving excellent soft focus effect and transparent touch. SOLUTION: This cosmetic features including a spherical particle having a multilayer structure which satisfies the expression: 0.5<=D <=100 (I), 1.3<=nk<=1.7 (II) and .|n2-n1|>=0.05 (III) when the average particle diameter (μm) and the refractive indexices polymers constituting respective layers are expressed by D and nk [the refractive index of the polymer constituting most outer layer is expressed by n1 and the refractive indexes of polymers constituting other layers are expressed by n2, n3...nk (n) is an integer of 2-10} in turn toward the inside of the particle], respectively.
