Abstract
The reaction to deposit the palladium nuclei by reducing the palladium complex adsorbing on the surface of the polyimide resin was examined using alkaline electrolyzed water containing sodium sulfate to which sodium ascorbate was added. As a result, the palladium nuclei could not form when they were used separately. But it has been confirmed that palladium nuclei formed when both of them coexisted. This palladium nuclei could be used as catalytic sites for the electroless nickel plating. The adhesive strength of the plated nickel layer was equivalent to that produced by a commercially available activator.
