To provide skin material suppressing temperature rise of various articles.SOLUTION: The skin material comprises a fiber assembly containing fibers which do not contain carbon black and have a single fiber diameter of larger than 1 μm and 5 μm or less. A cube with 0.1-0.5 mm of one side is cut out of an image obtained by observing the skin material by X-ray CT. The volume fraction which is a ratio of volume that fibers, which have a single fiber diameter of larger than 1 μm and 5 μm or less, included in the cube occupy is 3% or more and 20% or less, where the entire volume of the cube is 100%. Orientation tensor in a Z-axis direction is 0.42 or less.SELECTED DRAWING: Figure 1

    【課題】各種物品の温度上昇を抑制する表皮材を提供する。【解決手段】表皮材である。カーボンブラックを含まず、かつ単繊維径が1μmより大きく5μm以下の繊維が含まれた繊維集合体を備えている。表皮材をX線CTで観察して得られた画像から、1辺が0.1〜0.5mmの立方体を切り出して、立方体の全体の体積を100%とした場合に、前記立方体に含まれる前記単繊維径が1μmより大きく5μm以下の繊維が占有する体積の割合である体積率は3%以上20%以下である。Z軸方向の配向テンソルが0.42以下である。【選択図】図1
