Surface-treated material, method for producing the surface-treated material, and component formed by using the surface-treated material

A surface-treated material comprising a conductive substrate, and a surface treatment film which includes at least one layer of metal layers and is formed on the conductive substrate, wherein

• in cross-sectional observation of the surface-treated material, when portions between a portion of the conductive substrate and a portion of the surface treatment film are subjected to a line analysis with the use of STEM-EDX, and an obtained profile of detection intensity of each component of the surface-treated material is viewed, a maximum value of an intensity ratio of zinc to a main component of the surface treatment film is 1/4 or less, in a specific analysis range in which the intensity of the main component of the surface treatment film is equal to or higher than the intensity of the main component of the conductive substrate;
• and a ratio of a contact area to a test area is 85% or more as measured according to a tape test method defined in JIS H 8504:
