<p>A plating method for applying a secondary plating (electroless plating) onto a primary plated film (or a metal film) formed on a substrate for reliably executing the plating reaction at a higher deposition rate without requiring Pd-substitution treatment. The surface potential of the primary plated film is adjusted to be baser than the basest surface potential at which the surface current density of the primary plated film becomes 0 in the electroless plating solution for the secondary plating and, then, the secondary plating is effected. The invention further covers a pH-adjusting agent that is suited for carrying out the electroless plating method, a pretreatment solution for electroless plating that contains a reducing agent and a complexing agent, and an electroless plating bath.</p> |
