    • PROBLEM TO BE SOLVED: To provide an electroless-plated film having a fluorocarbon resin coating thereon, which is uniformly coated even on an article with a complicated shape or the inner surface of a pipe as is coated in a normal electroless plating process, and imparts high corrosion resistance to the surface even with a comparatively thin film; and also to provide a production method therefor.
      SOLUTION: The plated film comprises: an electroless-plated film or a composite electroless-plated film; and the fluorocarbon resin film with a film thickness of 5 μm or less formed thereon. The plated film having the fluorocarbon resin film thereon has such corrosion resistance that a sprayed period of time before the corroded amount reaches the rating No. 8 in a neutral salt spray test (JIS H 8502) is 150 hours or longer. The article has the above film at least on one part of the surface. The method for producing the plated film includes forming the fluorocarbon resin film with a film thickness of 5 μm or less, on the electroless-plated film or the composite electroless-plated film, by using a solution in which fluorocarbon resin particles are dispersed in water by a cationic surface active agent.
