Abstract
An insulating film-coated metal foil having on one or both surfaces thereof an organic-inorganic hybrid layer containing dimethylsiloxane and a metalloxane comprising a metal other than Si. Relative to the concentration [Si]of the Si at a depth of ¼t from the surface of the organic-inorganic hybrid layer in the thickness direction of the hybrid layer, the concentration [Si]of the Si at a depth of ¾t from the surface of the organic-inorganic hybrid layer in the thickness direction of the hybrid layer satisfies [Si]<[Si], and ([Si]−[Si])/[Si]is 0.02-0.23. Provided is a metal foil that can be used in solar cell substrates, flexible circuit substrates, etc., that exhibits surface flatness, pliability, insulating properties and thermal resistance properties, and that has a layer having a surface which is not susceptible to scratching by processes in which substrates are handled, such as conveyance and transshipment.
