CONDUCTIVE PARTICLE, PRODUCTION METHOD THEREOF, CONDUCTIVE MATERIAL AND CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a conductive particle which can reduce the connection resistance when used in an electrical connection between electrodes. ! SOLUTION: A conductive particle 1 comprises: a substrate particle 11; and a conductive layer 22 which is arranged on the surface of the substrate particle 11 and contains copper and tin. The conductive particle 1 is obtained by using a before-treatment particle in which a copper plated layer is arranged on the surface of the substrate particle 11, the outer surface of the copper plated layer of the before-treatment particle being subjected to substitution plating with tin. !
