CONDUCTIVE PARTICLE, CONDUCTIVE MATERIAL, AND CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a conductive particle which is capable of decreasing connection resistance when establishing electrical connection between electrodes, and enhancing connection reliability between the electrodes at high temperatures.SOLUTION: A conductive particle includes a base material particle, a first conductive layer, and a gold layer containing gold. The first conductive layer is disposed on a surface of the base material particle. The gold layer is disposed on an outer surface of the first conductive layer. A crystallite size in the gold layer exceeds 15 nm and does not exceed 300 nm.
