A particulate polyamide is provided. The particulate polyamide is porous and includes at least one of polyamide 4 and polyamide 3. In addition, the particulate polyamide has a particle diameter (d50) of from 10 μm to 1,000 μm and a particle diameter dispersion degree (Dv/Dn) of not greater than 3.0, wherein Dv represents the volume average particle diameter of the particulate polyamide, and Dn represents the number average particle diameter of the particulate polyamide. |
