PURPOSE: Conductive particles are provided to have excellent surface conductivity, durability, and heat resistance by physically and/or chemically combining two materials having conductivity, thereby being easily used as an electron packaging material such as an anisotropically conductive film, etc. CONSTITUTION: Conducive particles comprises a substrate particles, a carbon nanotube layer spread on a surface of the substrate particle, a plurality of metal nanoparticles combined with the carbon nanotube layer. The carbon nanotubes comprise a reactive group. The metal nanoparticles are combined with the carbon nanotube layer by covalent-bonding with the reactive group. A manufacturing method of the conductive particles comprises: a step of preparing the carbon nanotubes comprising the reactive group; a step of preparing a carbon nanotube-substrate composite particles by coating the surface of the substrate particle with the carbon nanotubes; and a step of accepting the metal nanoparticles into the carbon nanotube-substrate composite particle. |
