PROBLEM TO BE SOLVED: To obtain a flexible nonwoven fabric laminate having improved uniformity, excellent air permeability, water resistance and fluff resistance. SOLUTION: This nonwoven fabric laminate is a laminate comprising a spun-bond nonwoven fabric layer and a melt-blown nonwoven fabric layer in which one side or both sides of the surface layer is the spun-bond nonwoven fabric layer. The spun bond nonwoven fabric comprises an ethylenic polymer (a) having 0.85-0.97 g/cm3 density, <=3 Mw/Mn, two or more melting point peaks measured by a differential scanning calorimeter or a half value width of the highest melting point peak of a peak height of >=5 deg.C. The melt-blown nonwoven fabric is composed of the kind of resin selected from an ethylene homopolymer, a propylene/ethylene random copolymer, a resin composition of an ethylene homopolymer and a propylene-based polymer (c), a resin composition of an polyolefin-based elastomer and a propylene-based polymer (e) and a resin composition of an ethylenic polymer (f) and a polyethylene wax.
