<p>Disclosed is a method for advantageously remove a solvent A remaining in a porous polyamide fine powder which has been obtained by bringing a polyamide solution prepared by dissolving a polyamide in the solvent A into contact with a nonsolvent B for polyamides. Specifically, the solvent A is extracted and removed from the porous polyamide fine powder by bringing a nonsolvent C for polyamides, which is compatible with the solvent A at least at a temperature not less than 40°C, into contact with the porous polyamide fine powder at a temperature not less than 40°C.</p>
