PROBLEM TO BE SOLVED: To provide polyamide porous fine particles having more improved function and being an independent particulate powder of non-aggregation for a cosmetic raw material use, an optical film use in an electronic field, and a coating use, etc. SOLUTION: This polysiloxane-coated polyamide porous fine particle is disclosed that is produced by coating polysiloxane inside a pore and on a surface of a polyamide porous fine particle having a number-average particle diameter of 1-30μm and a BET specific surface area of 0.1-80 m<SP>2</SP>/g, before heat-treating at a temperature of <100°C, in which the polysiloxane is applied in an amount of≥1 wt.% based on the polyamide porous fine particle.
