This invention provides a nonwoven fabric laminate with a total basis weight of 30g/m2 or less, including a first spunbond nonwoven fabric (first SB nonwoven fabric) consisting of propylene-based polymers, a melt blown nonwoven fabric consisting of the propylene polymers laminated on the first SB nonwoven fabric, and a second spunbond nonwoven fabric (second SB nonwoven fabric) consisting of propylene-based polymers laminated on the melt blown nonwoven fabric. The nonwoven fabric laminate is characterized in that the basis weight of the first SB nonwoven fabric ranges from 3 to 25g/m2, the basis weight of the second SB nonwoven fabric ranges from 1 to 11g/m2, the ratio of the basis weight of the first SB nonwoven fabric to that of the second SB nonwoven fabric is 1.6 or more, the ratio of the thickness of the first SB nonwoven fabric to that of the second SB nonwoven fabric is 1.4 or more, the basis weight of the melt blown nonwoven fabric is less than 3g/m2, and the bonding area ratio is in a range of 6% to 25%.本發明提供不織布疊層體,其總單位面積質量為30g/m2以下,並包含,由丙烯聚合物所組成之第一紡粘不織布(第1SB不織布)、由丙烯聚合物所組成之熔噴不織布,其疊層於該第一紡粘不織布上,及由丙烯聚合物所組成之第二紡粘不織布(第2SB不織布),其疊層於該熔噴不織布上,其中,該第一紡粘不織布之單位面積質量為3~25g/m2之範圍內,該第二紡粘不織布之單位面積質量為1~11g/m2之範圍內,且第一紡粘不織布與第二紡粘不織布之單位面積質量比(即第一紡粘不織布之單位面積質量/第二紡粘不織布之單位面積質量)為1.6以上,以及第一紡粘不織布之厚度與第二紡粘不織布之厚度比(即第一紡粘不織布之厚度/第二紡粘不織布之厚度)為1.4以上,該熔噴不織布之單位面積質量為小於3g/m2,並其加壓接合面積率在於6~25%之範圍內。10‧‧‧不織布疊層體12‧‧‧MB不織布14‧‧‧第1SB不織布16‧‧‧第2SB不織布18‧‧‧熱熔黏接劑塗佈預定面
