PROBLEM TO BE SOLVED: To provide a new catalyst ink which can be treated simply by the small number of steps, while paying attention to an environment, and which can achieve cost reduction, and can be used as a pretreatment step for electroless plating.SOLUTION: A catalyst ink for forming a ground layer of an electroless metal plated film contains a hyperbranched polymer having an ammonium group on a molecular terminal and having a weight average molecular weight of 500-5,000,000, metal fine particles and alkoxysilane, a vinyl polymer having an amide structure on a side chain, and a thermosetting resin precursor. |
