PURPOSE: Provided are a conductive metallic fine particle ink for the metal wiring of a printed circuit board, which is excellent in stability, and a process for producing the conductive metallic fine particle ink. CONSTITUTION: The conductive metallic fine particle ink is produced by dispersing metallic fine particles with a diameter of less than 100 nanometer in an alcohol medium or a water-alcohol medium, wherein the alcohol comprises at least one alcohol with the carbon number of less than 5. The metallic fine particles are produced by preparing the metallic fine particles with a diameter of less than 100 nanometer by a colloidal method using the ionization tendency and then removing ions contained in the solution. Or the metallic fine particles are produced by a vacuum metallizing method. |
