<P>PROBLEM TO BE SOLVED: To provide ink for a wiring material, having excellent dispersion stability as ink and excellent preservation stability, and to provide a method for producing the ink. <P>SOLUTION: The ink for the wiring material is produced by reducing a metal ion in a mixed solution of the metal ion and an aqueous solution of an electroconductive polymer to afford a metal colloid, wherein the electroconductive polymer is at least one kind of a polyaniline, a polythiophene and derivatives thereof. The circuit board is made by using the ink for wiring. <P>COPYRIGHT: (C)2008,JPO&INPIT |
