<p>An object of the invention is to provide a spunbonded nonwoven fabric which has excellent flexibility, feel to the touch, forming properties and productivity without deteriorating the stretchability of a spunbonded nonwoven fabric containing a low crystalline polypropylene. A spunbonded nonwoven fabric-laminated multilayer structure of the invention includes an elastic nonwoven fabric which contains a low crystalline polypropylene satisfying (a) to (f) and an extensible spunbonded nonwoven fabric having an elongation at maximum load of not less than 50% in at least one direction, the extensible spunbonded nonwoven fabric being laminated on at least one surface of the elastic nonwoven fabric: (a) [mmmm] = 20 to 60 mol%, (b) [rrrr]/(1 - [mmmm]) ‰¤ 0.1, (c) [rmrm] > 2.5 mmol%, (d) [mm] × [rr] / [mr] 2 ‰¤ 2.0, (e) mass average molecular weight (Mw) = 10,000 to 200,000, (f) molecular weight distribution (Mw/Mn) < 4.</p> |
