<p>An object is to provide a metal particle which is a non-nucleated, spherical porous material having continuous open pores, and which is formed from dendritic crystals which have grown uniformly outward from the center without requiring a nucleating agent, and a method for producing the same. A method for producing a metal particle comprises the steps of: mixing a metal salt and a polycarboxylic acid in a liquid phase; adding a reducing agent to the resultant mixture to deposit metal particles; and drying the deposited metal particles. The metal particle produced by the method, which is a non-nucleated, spherical porous material having continuous open pores, is unlikely to suffer bonding or aggregation of the metal particles and exhibits excellent dispersibility, and, when the metal particle is used in a conductive composition, such as a conductive paste, a cured product having satisfactory conduction properties can be obtained at a relatively low temperature, making it possible to easily control the specific gravity or resistance.</p> |
