Article comprising plated component

Abstract

An article at least comprising two components contacting with each other, in which at least part of a surface of at least one of the two components being plated, is provided, which is excellent in plating adhesion and impact resistance and thus is hard to be damaged on the plated surface and excellent in appearance even when one of the two components is brought into contact with the plated part of the other component, and is preferably suppressed in occurrence of unpleasant sounds such as squeaking noise. At least one of the two components of the article is formed of a thermoplastic resin composition (X) comprising a rubber-reinforced aromatic vinyl resin (A) in at least part of the portion that contacts the plated portion of the other component.
