Chromium-plated component and production method for same

A chromium-plated part comprising:

• a base having a surface layer comprising copper or a copper alloy;
• a first nickel plating layer formed on the surface layer of the base;
• a second nickel plating layer formed on the first nickel plating layer;
• and
• a trivalent chromium plating layer formed on the second nickel plating layer, the second nickel plating layer having an anode potential of −215 to −290 mV at a current density of 0.1 mA/cm2, and
• the first nickel plating layer having an electric potential 15 to 150 mV lower than that of the second nickel plating layer.

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

• forming a first nickel plating layer on a surface layer of a base, the surface layer comprising copper or a copper alloy;
• forming a second nickel plating layer on the first nickel plating layer;
• and
• forming a trivalent chromium plating layer on the second nickel plating layer,
• wherein the second nickel plating layer has an anode potential of −215 to −290 mV at a current density of 0.1 mA/cm2, and
• the first nickel plating layer has an electric potential 15 to 150 mV lower than that of the second nickel plating layer.
