ABSTRACT:
A method of production of conductive particles able to suppress growth of the conductive particles at the firing stage, able to effectively prevent spheroidization and electrode disconnection, able to effectively suppress a drop in electrostatic capacity, and able to efficiently produce core particles covered by thin coating layers without abnormal segregation of the coating layer metal particularly even when the internal electrode layers are reduced in thickness. A method of producing conductive particles comprising cores51having nickel as their main ingredients and coating layers52covering their surroundings. A core powder, a water-soluble metal salt containing a metal or alloy forming the coating layers52, and a surfactant (or water-soluble polymer compound) are mixed to deposite by reduction a metal or alloy for forming the coating layers52on the outer surfaces of the core powder. The metal or alloy forming the coating layers52has at least one type of elements selected from Ru, Rh, Re, and Pt as a main ingredient.
