5 Claims

1. A functional fiber sheet comprising synthetic fiber, at least one face thereof being coated with a physically vapor-deposited transparent film comprising metallic oxides, wherein said metallic oxides comprise a mixture of an ordinary oxide as a main component and a small amount of oxides having a lower valence than said ordinary oxide as a secondary component, wherein said metallic oxide is titanium oxide, its ordinary oxide being a tetravalent oxide and said lower valence oxides being divalent or trivalent oxides, and the amount of lower valence oxides to the total amount of the metallic oxides is 0.1 to 20 wt %.
