PROBLEM TO BE SOLVED: To provide a catalyst-imparting solution for electroless plating which is capable of imparting the catalyst in a neutral pH region to a work to be plated weak to acid or alkali. SOLUTION: The catalyst-imparting solution contains soluble palladium complex generated by the reaction of a complexing agent containing no nitrogen atoms as ligand with palladium salt and chlorine ions and the pH value is in a region of 5 to 9. Palladium ions are taken in by soluble palladium complex to prevent precipitation of metal palladium, the palladium complex has adequate stability. Metal palladium is substitute-precipitated on the work without corrosion of the work weak to acid or alkali, and catalyst is imparted thereby. COPYRIGHT: (C)2005,JPO&NCIPI
