PROBLEM TO BE SOLVED: To provide a fiber sheet which hardly inhibits a flexure movement of a portion even when the fiber sheet is wound to a portion where flexure movement and extension movement are performed, such as a joint part, and a bandage using the same.SOLUTION: There are provided: a fiber sheet in which, when a thickness of single sheet measured according to an A method of JIS L 1913 is T1(mm), and thickness when the three sheets are laminated measured according to the same condition is T3(mm), a following formula {T3/(3×T1)}×100≤85(%), is satisfied and a bandage using the same. The fiber sheet has preferably, a basis weight of 50 g/m2 or higher.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】関節部のような曲げ伸ばしをする部位に巻き付けても、当該部位の曲げ動作を阻害しにくい繊維シート、及びこれを用いた包帯を提供する。【解決手段】JIS L 1913のA法に準拠して測定される1枚の厚みをT1〔mm〕、同条件にて測定される3枚重ねたときの厚みをT3〔mm〕とするとき、次式:{T3/(3×T1)}×100≦85〔%〕を満たす繊維シート、及びそれを用いた包帯である。繊維シートは、目付が50g/m2以上であることが好ましい。【選択図】なし
