<p><P>PROBLEM TO BE SOLVED: To provide metal nanoparticles which easily and quickly form a conductive pattern on a resin substrate of low heat resistance, a manufacturing method therefor a water dispersion material, a manufacturing method of a printed wiring-electrode, and a printed circuit board-device. <P>SOLUTION: The metal nanoparticles include either silver or a silver alloy, and an iron compound, and have a mean particle diameter of 1 nm to 100 nm. In a preferable embodiment, the content of iron atoms in the iron compound is 0.01 atom% to 10 atom% with respect to either of the silver or the silver alloy. The water dispersion material consists of the metal nanoparticles. In the manufacturing method of the printed wiring-electrode, the water dispersion material is applied by coating on the resin substrate, then it is dried at 200°C or less. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
