Problem to be solved: to provide an operation sheet which can prevent blood or fluid from dripping onto the floor surface during surgery and use it.The surgical sheet of the present invention is an operation sheet in which the nonwoven fabric is exposed to the surface, and the nonwoven fabric has a unidirectional orientation layer in which the fiber is oriented in one direction.It is preferable that the surgical sheet has a substantially rectangular shape and the orientation direction of the unidirectional orientation layer is substantially coincident with the longitudinal direction of the surgical sheet.In addition, it is preferable that the nonwoven fabric contains hydrophilic fibers, and that the hydrophilic fibers are fibers having two or more kinds of surfactants having different non-ionic fibers.In addition to the non-woven fabric, it is preferable to have a film.The surgical sheet of the present invention is preferably used to cover the human body so that the nonwoven fabric is exposed and the orientation direction of the unidirectional orientation layer is substantially coincident with the vertical direction of the human body.Diagram【課題】 手術時に、従来よりも血液や体液が床面へ滴り落ちるのを抑制できる手術用シート、及びその使用方法を提供すること。【解決手段】 本発明の手術用シートは、不織布が表面に露出した手術用シートであり、前記不織布は繊維が一方向に配向した一方向配向層を有する。また、手術用シートが略長方形状を有し、しかも一方向配向層の配向方向と手術用シートの長手方向とが略一致するのが好ましい。更に、不織布が親水性繊維を含むことが好ましく、親水性繊維が非親水性繊維にイオン性の異なる２種類以上の界面活性剤が付与された繊維であるのが特に好ましい。更に、不織布に加えてフィルムを有するのが好ましい。本発明の手術用シートは、不織布が露出するとともに、一方向配向層の配向方向と人体の上下方向とが略一致するように人体を覆って使用するのが好ましい。【選択図】 図２
