Chromium plated component and method for producing same

A chromium-plated part comprising:

• a base having a surface layer comprising copper or a copper alloy;
• a bright nickel plating layer formed on the surface layer of the base;
• a noble-potential nickel plating layer formed on the bright nickel plating layer and having an electric potential 30 to 180 mV higher than that of the bright nickel plating layer;
• and
• a trivalent chromium plating layer formed on the noble-potential nickel plating layer.

A method for manufacturing a chromium-plated part, the method comprising:

• forming a bright nickel plating layer on a surface layer of a base, the surface layer comprising copper or a copper alloy;
• forming a noble-potential nickel plating layer on the bright nickel plating layer, the noble-potential nickel plating layer having an electric potential 30 to 180 mV higher than that of the bright nickel plating layer;
• and
• forming a trivalent chromium plating layer on the noble-potential nickel plating layer.
