To provide a plating or electroforming method improved in bright nickel surface treatment in applying a replating onto a primary bright nickel plating, a method for forming a lamination plated tight adhesive test specimen as well as a method for improving the tight adhesion strength of the plating in the plating or electroforming of the bright nickel plating to each other.

The plating or electroforming method of determining the energization start time in secondary plating when subjecting a primary plating film to secondary plating after a plating work is subjected to the replating or additional stages exclusive of the plating, such as resist pattern forming as the non-energization time for a specified period after the work is immersed in the plating liquid before the start of the plating. The method for forming the plating adhesive test specimen comprises: subjecting the work to the primary plating by this method, then subjecting the work to the secondary plating after the work is subjected to activation treatment, and only the one end of the plating surface is subjected to release treatment.
