PURPOSE:To form an electrically conductive paste in which migration and oxidation of electrically conductive metallic particles are prevented and which is inexpensive and can be applied to practical use, by kneading specified electrically conductive particles with a resin compsn. CONSTITUTION:This electrically conductive paste can be formed by kneading a resin compsn. with fine electrically conductive metallic particles obtd. by forming a film composed of a second electrically conductive metal on the surface of a nucleus composed of a first electrically conductive metal. Pref. said second conductive metal is composed of a metal which makes migration much more difficult than the first metal. An example of the first conductive metal is copper and an example of the second conductive metal is nickel.
