<P>PROBLEM TO BE SOLVED: To provide a complex polyamide porous fine particle having in combination the features of polyamide porous fine particles and antibacterial materials, with an industrially easy technique. Ž<P>SOLUTION: The complex polyamide porous fine particle supports an antibacterial material on the outer periphery surface and/or inside the pore of the polyamide porous fine particle having a number-average particle diameter of 1-30 μm, the ratio (PDI) of a volume-average particle diameter to a number-average particle diameter of 1.0-2.0, a mean pore diameter of 0.01-0.5 μm, a BET specific surface area of 0.1-80 m<SP>2</SP>/g, and a degree of porosity (RI) of 5-100.
