A method of forming a metal fine particle pattern including forming a polymerization initiation layer on a support, wherein a polymer which has, in its side chain, a cross-linking group and a functional group having the ability to initiate polymerization is fixed by a cross-linking reaction, forming a graft polymer region in a pattern on the surface of the polymerization initiation layer, wherein the graft polymer layer has the ability to contain a metal ion or a metal salt, adding a metal ion or a metal salt to the graft polymer layer, and thereafter reducing the metal ion or a metal ion in the metal salt to form a metal fine particle dispersion region; and a method of forming an electroconductive pattern using the method of forming a metal fine particle pattern.
