PROBLEM TO BE SOLVED: To provide a nonwoven fabric including a plurality of projection parts in which different heights are excellently formed, and a method for manufacturing the same.SOLUTION: A nonwoven fabric 10 which comprises recessed parts 4 in which uneven surfaces 5 of the nonwoven fabric 10 in which a plurality of junctions 3 between non-heat shrinkage fiber layers 1 and heat shrinkage fiber layers 2 are separately laminated are made due to that the junctions 3 are recessed from the non-heat shrinkage fiber layers 1 to the heat shrinkage fiber layers 2 and high projection parts 6 having a solid dome surrounded with the junctions 3, and low projection parts 7 lower than the high projection parts 6 is such that: the high projection part 6 is arranged in a large polygonal area 8 divided by the junction 3, an end part, and a linear part connecting an interval between the end parts the low projection part 7 is arranged in a small polygonal area 9 divided by the junction 3, the end part, and the linear part connecting an interval between the end parts, and having an area smaller than that of the large polygonal area 8 and the linear part 2 is arranged obliquely to the fiber orientation direction of the non-heat shrinkage fiber layer 1 and a direction orthogonal to the fiber orientation direction of the non-heat shrinkage fiber layers 1. A method for manufacturing the nonwoven fabric is also provided.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】異なる高さが良好に形成された凸部を複数備える不織布及び該不織布の製造方法の提供。【解決手段】非熱収縮繊維層1と熱収縮繊維層2との接合部3が複数互いに離間して積層した不織布10の凹凸面5は接合部3が非熱収縮繊維層1から熱収縮繊維層2に窪んでなる凹部4と、接合部3に囲まれた立体ドーム構造を有する高凸部6及び高凸部6よりも高さの低い低凸部7とからなり、高凸部6は接合部3と端部、端部間を繋いだ直線部とで区画される大多角形領域8に配されており、低凸部7は接合部3と端部、端部間を繋いだ直線部とで区画される大多角形領域8よりも面積の小さい小多角形領域9に配されており、直線部2は、非熱収縮繊維層1の繊維配向方向及び非熱収縮繊維層1の繊維配向方向と直交する方向に対して傾斜した配置にされている不織布10及びその製造方法。【選択図】図1
