Abstract: PURPOSE: Provided are multi-layered conductive polymer composite particles used as conductive particles for producing anisotropic conductive connection sheets, which is excellent in connection reliability and working efficiency. CONSTITUTION: The multi-layered conductive polymer composite particles are produced by a process comprising the steps of: forming a metal layer(2) on the surface of a spherical polymer resin particle(1); adding the metal coated polymer resin particle and a binder to alcohol and performing an ultrasonic dispersion and then evaporating the alcohol to treat the surface of the metal; dissolving the surface-treated metal-coated polymer resin particle and a thermoplastic resin(3) in a non-water soluble solvent and performing an ultrasonic dispersion to produce an emulsion; adding a nonionic emulsifier to the emulsion and freezing and drying. The thermoplastic resin(3) has a particle diameter of 5-30% based on the metal coated polymer resin particle.
