Abstract

Composite polyamide fine particles include a polyamide (A1) which has a melting point or a glass transition temperature of over 100° C. and a polymer (A2) which is different from the polyamide (A1). The composite polyamide fine particles have: a dispersion structure in which a plurality of domains each having an average particle diameter of 0.05 to 100 μm whose main component is the polymer (A2) are dispersed in a polyamide (A1) based matrix; an average particle diameter of 0.1 to 500 μm; and a sphericity of 80 or more.
