摘要： PROBLEM TO BE SOLVED: To develop a method for forming a dense metallic film on the surface of an object at a relatively low cost without using a noble metal active catalyst or a noble metal paste. SOLUTION: The method for forming the metallic film includes the steps of preparing the object 2 having a template film 10 including a first functional group 4 disposed in a desired pattern, on the surface, forming a supersaturation solution 14 of metal ion, forming metal ultrafine particles 16 in the solution by reducing the metal ion by a reducing agent, dipping the object 2 in the supersaturation solution 14, charging the metal ultrafine particles 16 and the first functional group 4 in the supersaturation solution to positive or negative so as to electrostatically bond them to each other, and forming the metallic film 20 having the pattern shape on the surface of the object by electrostatically bonding the metal ultrafine particles 16 to the first functional group 4 of the template film 10. Since the metal ultrafine particles naturally formed in the supersaturation solution are used, high density/highly minute metallic film can be formed. The thickness of the film can be controlled by the dipping time of the object in the supersaturation solution. COPYRIGHT: (C)2004,JPO&NCIPI

As a result, the film thickness of an electrode film thinner than the grain size cannot be obtained by a conventional globular metal power but the formation of the thin film below about 0.3 μm can be realized and the contribution can be made to manufacturing of the supermultilayered ceramic electronic components and the contribution to the cost reduction is made possible by using the scaly metal particulates 2.
