摘要： A method for producing conductor fine particles in which the advantages of conventional vapor phase method and liquid phase method are utilized while eliminating the drawbacks of both methods remarkably. Furthermore, definite guidelines and measure for improvement are given to the greatest problems common to the vapor phase method and liquid phase method, i.e., enhancement in quality of the unit fine particle and a fine particle production method controllably temporarily and regionally. The method for producing conductor fine particles comprises a step for applying a voltage to a pair of electrode consisting of a positive electrode and a negative electrode arranged in conductive liquid and generating plasma in the vicinity of the negative electrode, and a step for producing conductor fine particles by melting the metal material of the negative electrode and then re-solidifying.
