The present invention relates to a conductive particle including: a resin particle; a first plating layer provided on a surface of the resin particle; and a second plating layer provided on the first plating layer having a protrusion on an outer surface thereof, wherein the protrusion covers 93-100% of an area of the second plating layer, and includes: a first layer having a length of 100-300 nm and a second protrusion having a length less than 100 nm; the first protrusion covers 70-90% of the area of the second plating layer; and the second protrusion covers 10-30% of the area of the second plating layer. The protrusion is equally divided in a longitudinal direction into a base part, an intermediate part, and an end part; and if A is an average diameter of the base part, B is an average diameter of the intermediate part, and C is an average diameter of the end part, the relationship between A, B and C is A > B > C. |
