Method for producing a conductive particle, the conductive paste and a method of manufacturing an electronic component

In particular, even if each thickness of the internal electrode layer is made thin to suppress the grain growth of the conductive particles in the firing step, spheroidizing, electrode discontinuity effectively prevented, effectively suppressing the deterioration of the capacitance possible, yet there is no abnormal segregation of the metal-coating layer, the method for fabricating a conductive particle of core particles coated with a thin coating layer can be produced efficiently. A core portion 51 mainly composed of nickel, a method for fabricating a conductive particle and a coating layer 52 covering the periphery thereof. A powder core, and a water-soluble metal salt containing a metal or alloy forming the coating layer 52, a surfactant (or a water-soluble polymer compound) and by mixing, on the outer surface of the powder core, the coating layer 52 forming metal or alloy is reduced and precipitated. Metal or alloy forming the coating layer 52 has Ru, Rh, at least one element selected from Re and Pt as main components.
