Abstract:
1. A plating method comprising: carrying out pretreatment of a surface of a base metal of a substrate using a pre-treatment liquid containing a surface activating agent for activating the surface of the base metal and an excessive etching inhibitor for inhibiting excessive etching of the base metal; after said carrying out pretreatment of the surface of the base metal of the substrate, contacting the substrate with a catalytic treatment liquid so as to apply a catalyst to the surface of the base metal of the substrate; after said contacting the substrate with the catalytic treatment liquid, forming a metal film by electroless plating on the surface of the base metal of the substrate; and after said contacting the substrate with the catalytic treatment liquid, carrying out a post-catalyzation treatment of the surface of the base metal by jetting a post-treatment liquid toward the surface of the base metal of the substrate so as remove any excess of the excessive etching inhibitor.
