ABSTRACT:
To an electroless gold plating bath comprising a water-soluble gold compound, a complexing agent, and a reducing agent is added a small amount of polyvinyl pyrrodidone. The bath allows a satisfactory gold plating film to be formed on metal portions on a non-conductive substrate without plating spread.
