To provide a fiber layer containing fiber assembly and liquid formulation which is used to be applied to skin, in which a coating film with controlled moisture vapor permeability is obtained by making the basis weight of the fiber assembly and the permittivity of the liquid formulation are set to a predetermined range.SOLUTION: A coating film for human skin equipped with a fiber layer. The fiber layer includes a fiber assembly in which fiber by water-insoluble polymer having the fiber diameter of 50nm or more and less than 10000nm is deposited and liquid formulation X present among fibers and on the surface of fiber in the fiber assembly, the basis weight Q of the fiber assembly is 0.08 mg/cmor more and 1.0 mg/cmor less, the liquid formulation X has the basis weight P of 0.5 mg/cmor more and 2.3 mg/cmor less, and relative permittivity of 1.0 or more and 27 or less, contains component (a) oil agent which has relative permittivity of 0.5 or more and 20 or less and is a liquid state at 20°C, and the content of component (b) polyol in liquid formulation X at 20°C liquid state is 50 mass% or less.SELECTED DRAWING: None【課題】皮膚に適用するための、繊維集合体と液剤とを含む繊維層であって、繊維集合体の坪量と液剤の誘電率を所定の範囲とすることにより、透湿度がコントロールされた被膜を得る。【解決手段】 繊維層を備えるヒト皮膚用被膜であって、 繊維層は繊維径が５０ｎｍ以上１００００ｎｍ未満の水不溶性ポリマーによる繊維が堆積している繊維集合体と、繊維集合体における繊維間及び繊維の表面に存在する液剤Ｘを備えており、 前記繊維集合体の坪量Ｑは０．０８ｍｇ／ｃｍ2以上１．０ｍｇ／ｃｍ2以下であり、 前記液剤Ｘは、坪量Ｐが０．５ｍｇ／ｃｍ2以上２．３ｍｇ／ｃｍ2以下、比誘電率が１．０以上２７以下であり、成分（ａ）２０℃で液状の比誘電率が０．５以上２０以下の油剤を含有し、かつ、成分（ｂ）２０℃で液状のポリオールの液剤Ｘ中の含有量が５０質量％以下であるヒト皮膚用被膜。【選択図】なし
