PROBLEM TO BE SOLVED: To provide a manufacturing method of a conductive particle capable of preventing a conduction failure, and of reducing a resistance value; to provide a conductive particle; and to provide an anisotropic conductive material. SOLUTION: This manufacturing method of this conductive particle 1 having projections 2 on the surface thereof comprises: a process 1 for forming a nickel-plated layer with positive or negative charge charged thereon on the surface of a core particle; a process 2 for attaching a chelate agent having a functional group A and a reactive functional group B in every molecule to the surface of the nickel-plated layer through the functional group A; a process 3 for binding a resin fine particle or inorganic fine particle with charge opposite to the charge charged on the nickel-plated layer charged thereon to the surface of the nickel-plated layer through the reactive functional group B of the chelate agent; and a process 4 for coating the resin fine particle or inorganic fine particle and the nickel-plated layer with metal plating by an electrodeless plating method.
