Provided are composite polyamide particles and a method for producing the same, the particles comprising a polyamide (A1) which has a melting point or a glass transition temperature of over 100°C and a resin (A2) which is different from the polyamide (A1). The composite polyamide particles have: a dispersed structure in which a plurality of domains are dispersed in a polyamide (A1) based matrix, the main component of the domains being the resin (A2) with an average particle size of 0.05 to 100 mum; an average particle size of 0.1 to 500 mum; and a sphericity of 80 or more. The present invention provides: novel composite polyamide particles in which excellent tenacity, shock resistance, chemical resistance, etc. intrinsic to polyamide particles are not impaired and which have various properties and characteristics such as high tenacity, shock resistance and heat resistance that cannot be achieved with resin particles comprising a single polyamide; and a method for industrially advantageously producing the composite polyamide particles without being limited by the types of resin to be composited. |
