Polyamide resin fine particles suitable for cosmetics, consisting of powdery particles which are made of a polyamide resin having a relative viscosity of 1.70 to 2.35 and have spherical shape, porous surfaces, and oil absorption of 115 to 200 mL/g. The fine particles can be produced by dissolving a polyamide resin in a solvent, forming a liquid membrane from the obtained solution on the surface of a planar or filament-like member, and then cooling the liquid membrane to precipitate the polyamide resin in the form of particles. |
