PROBLEM TO BE SOLVED: To provide a metal pattern forming method that forms a metal pattern by electroless plating technique, the method forming a pattern excellent in adhesion to a substrate and excellent in a fine line drawing property, and to provided the metal pattern formed by using the method.SOLUTION: In the method of printing a pattern part on a substrate by an inkjet system using an ink containing a catalyst and drying it, and forming the metal pattern by electroless plating processing on the pattern part, the catalyst is a soluble palladium metal complex, the ink containing the catalyst has a pH of 10.0-14.0, and the printed pattern part before the electroless plating processing has a surface roughness Ra of 30 to 45 nm. |
