PROBLEM TO BE SOLVED: To provide a nonwoven fabric with conflicting two properties of flexibility and rigidity.SOLUTION: A nonwoven fabric in double layer structure comprises a continuous fiber nonwoven fabric on one side and a short fiber web on the other side. A continuous fiber constituting the continuous fiber nonwoven fabric has a cross-sectional shape in which four substantial Y-shape on upper, lower, right and left sides are connected at their lower ends and has single fiber fineness of 10 decitex or more. The continuous fiber nonwoven fabric has many holes made by punching. The short fiber web is subject to an interlacing treatment, which interlaces constituting fibers in the short fiber web with each other to unify the constituting fibers, and interlaces the short fibers with continuous fibers constituting the continuous fiber nonwoven fabric to unify the short fiber web and the continuous fiber nonwoven fabric. The short fibers interlacing with the continuous fibers exist on a surface side of the continuous fiber nonwoven fabric.SELECTED DRAWING: Figure 2 【課題】柔軟性と剛性との相反する性能を具備する不織布の提供【解決手段】片面が長繊維不織布、他面が短繊維ウェブにより構成される２層構造不織布であり、該長繊維不織布を構成する長繊維の横断面形状が、略Ｙ字の下端で上下左右に連結した形状であり、その単糸繊度が１０ｄｔｅｘ以上であり、該長繊維不織布は、穿孔による孔を多数有するものであり、短繊維ウェブは、交絡処理が施されることにより、短繊維ウェブ内の構成繊維同士が交絡一体化しているとともに、長繊維不織布を構成する長繊維に絡み付くことにより短繊維ウェブと長繊維不織布とが一体化するとともに、長繊維に絡み付いた短繊維が長繊維不織布表面側にも存在している２層構造不織布。【選択図】図２
