Abstract

A black plated resin part includes a resin base material, an underlying plating layer including a copper plating layer and a nickel plating layer formed in this order on the resin base material, a black chromium plating layer formed on the nickel plating layer, formed of trivalent chromium, and having a film thickness of not less than 0.15 μm, and a corrosion resistant film formed on the black chromium plating layer, formed of chromic phosphate or molybdenum phosphate, and having a film thickness of not less than 7 nm. A brightness of the black chromium plating layer seen through the corrosion resistant film is expressed by an L* value of not more than 54 based on the L*a*b* color system.
