CONDUCTIVE PARTICLE, CONDUCTIVE MATERIAL AND CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a conductive particle capable of lowering connection resistance between electrodes when used for connection between electrodes.SOLUTION: The conductive particle 1 comprises: a base particle 2; a conductive portion 3 arranged on the surface of the base particle 2 and having a plurality of protrusions 3a on the outer surface; and multiple core material 4 embedded in the conductive portion 3. The core material 4 is disposed in the inside of the protrusion 3a of the outer surface of the conductive portion 3. The core material 4 has a non-spherical shape. The material of the core material 4 is zinc oxide, aluminum oxide, titanium oxide or tungsten carbide.
