There is provided by the present invention a nonwoven fabric laminate which comprises a first spunbonded nonwoven fabric comprising a propylene-based polymer (first SB nonwoven fabric), a melt blown nonwoven fabric comprising a propylene-based polymer and laminated on the first spunbonded nonwoven fabric, and a second spunbonded nonwaven fabric (second SB nonwoven fabric) comprising a propylene-based polymer and laminated on the melt blown nonwoven fabric, and which has overall basis weight of not more than 30 g/m 2 , wherein the basis weight of the first SB nonwoven fabric is in the range of 3 to 25 g/m 2 , the basis weight of the second SB nonwoven fabric is in the range of 1 to 11 g/m 2 , the ratio of the basis weight of the first SB nonwoven fabric to the basis weight of the second SB nonwoven fabric is not less than 1.6, the ratio of a thickness of the first SB nonwoven fabric to a thickness of the second SB nonwoven fabric is not less than 1.4, the basis weight of the melt blown nonwoven fabric is less than 3 g/m 2 , and the compression bond area ratio is in the range of 6 to 25%. |
