CONDUCTIVE PARTICLES, CONDUCTIVE MATERIAL AND CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide conductive particles in which, when electrically connecting between electrodes, the connection resistance can be reduced, and connection reliability can be improved.SOLUTION: A conductive particle 1 comprises a base material particle 2, and a conductive part 3 disposed on the surface of the base material particle 2. The base material particle 2 comprises an organic core 2 A, and an inorganic shell 2B disposed on the surface of the organic core 2 A. The conductive part 3 has a plurality of projections 3a on the external surface. The material of the external surface of the conductive part 3 is ductile metal with 5% or more and 65% or less of elongation percentage at 23°C.
