PROBLEM TO BE SOLVED: To provide a substrate treating method for carrying metal micro-particles to form a plated layer on a circuit pattern or a TSV in various substrates so that finer treatment than the prior art can be made to form a stable plated layer.SOLUTION: A substrate treating method for bringing a substrate and a colloidal solution containing metal particles into contact so as to carry metal particles to become a catalyst for forming a plated layer on the substrate, wherein the colloidal solution contains metal particles of Pd having a particle diameter of 0.6 nm to 4.0 nm, an interface distance of a (111) plane of 2.254 Å or more. This substrate surface before treated is enabled to enhance the binding power of Pd particles by forming an organic layer such as SAM.

PROBLEM TO BE SOLVED: To provide a method of manufacturing a touch panel.SOLUTION: A method of manufacturing a sensing electrode of a touch panel includes the steps of: forming a non-conductive mesh skeleton by applying an electrospinning solution onto a transparent substrate with an electrospinning method; and forming an electrode layer by performing electroless plating processing on the non-conductive mesh skeleton. Uniform conductivity for the whole electrode layer can be realized by preventing ununiform conductivity in the mesh skeleton by forming the non-conductive mesh skeleton using the electrospinning method and then forming the electrode layer using the electroless plating.

PROBLEM TO BE SOLVED: To provide a method which can roughen the surface of a substrate without using a chemical etching agent so that the substrate can secure a sufficient adhesion strength to an electroless-plated film.SOLUTION: This manufacturing method includes: the first step of forming the substrate 1; the second step of irradiating either the surface of the substrate or only a portion 1a to become a circuit out of the surface, with the first laser light 2 to roughen either of them; the third step of imparting a catalyst 3 to the surface of the substrate; the fourth step of drying the substrate; the fifth step of irradiating a portion 1b which does not become the circuit with the second laser light 4 to lower or eliminate the function of the catalyst in the portion which does not become the circuit; and the sixth step of forming an electroless-plated film on the portion to become the circuit.

PROBLEM TO BE SOLVED: To provide a method and apparatus for producing a conductive material, which can produce the conductive material having a patterned fine conductive metal layer with high efficiency. SOLUTION: A photosensitive film having a silver salt emulsion layer containing silver salt on a transparent support 16 is exposed to be developed to form a metal silver portion 20. Then, the metal silver portion 20 is used as a cathode in solution containing metal ions for energizing a material 24 to be plated. Then, electroless plating treatment is applied to the material 24 to be plated after energized, to support a plated layer 34 only on the metal silver portion 20. The metal ions in the solution containing the metal ions are preferably copper, nickel, cobalt, or tin ions. COPYRIGHT: (C)2009,JPO&INPIT
