<p>A multilayer elastic film which comprises a layer (A) formed of polypropylene (A) satisfying the following (a) to (d) and a layer (B) formed of a polyolefin resin or a polyolefin resin composition, and also satisfies the following formula (1): (a) (mmmm) = 20 to 60% by mol, (b) (rrrr)/(1-(mmmm))‰¤0.1, (c) (rmrm)>2.5% by mol, and (d) (mm)×(rr)/(mr) 2 ‰¤2.0; and Y‰¤600/X (1), wherein Y (%) = crystallinity of the resin or the resin composition to constitute the layer (B), and X (%) = total thickness of the layer (B)/total thickness of the multilayer elastic film × 100.</p> |
