    • Provided is a nonwoven fabric substrate (1) in which ridges (2) and grooves (3) are alternately formed at positions corresponding to each other on each of both surfaces (1a, 1b), and apertures (4) penetrating the grooves (3) of both surfaces are formed. The ridges (2) and the grooves (3) extend parallel to each other. The ridges (2) and the grooves (3) extend in a direction intersecting with each of a pair of both sides (1c, 1d) extending in parallel of the nonwoven fabric substrate (1). In planar view, each of the grooves (3) alternately includes an aperture portion (3h) which has a plurality of the apertures (4), and a non-aperture portion which has no aperture (4) and is longer than a distance between the nearest end portions of the adjacent apertures (4) in the aperture portion (3h), and arrangement patterns of the aperture portion (3h) and the non-aperture portion (3n) provided in the adjacent grooves (3) are different from each other. When the nonwoven fabric substrate (1) is seen in planar view, the nonwoven fabric substrate (1) has an aperture region (11) formed by the aperture portion (3h) of the plurality of grooves (3), and a non-aperture region (12) formed by the non-aperture portion (3n), and the aperture region (11) and the non-aperture region (12) are arranged in a predetermined pattern.
    • 本发明提供一种在两面(1a,1b)中的每一个上彼此相对应的位置上交替形成脊(2)和沟槽(3)的无纺布基材(1),穿过凹槽(3)的孔(4) )形成。 脊(2)和槽(3)彼此平行延伸。 脊(2)和槽(3)在与无纺布基板(1)平行的一对两侧(1c,1d)的交叉的方向上延伸。 在平面图中,每个沟槽(3)交替地包括具有多个孔(4)的开口部分(3h)和不具有孔径(4)并且长于第 开口部(3h)中的相邻孔(4)的最近端部以及设置在相邻槽(3)中的开口部(3h)和非开口部(3n)的配置图案各自不同 其他。 当在平面图中看到无纺布基材(1)时,无纺布基材(1)具有由多个凹槽(3)的开口部分(3h)形成的开口区域(11)和非孔径 由非开口部分(3n)形成的区域(12)和开口区域(11)和非开口区域(12)以预定图案布置。
