Abstract
Provided is a stretchable laminate that achieves both a weight reduction and an extension strength, and that can be stably produced. Also provided is an article including such stretchable laminate. The stretchable laminate of the present invention includes: an elastomer layer; and an olefin-based resin layer arranged on at least one side of the elastomer layer, wherein when a longitudinal direction of the stretchable laminate is defined as an MD direction and a direction perpendicular to the longitudinal direction is defined as a CD direction, a ratio [10% extension strength in MD direction (N/30 mm)]/[basis weight (gsm)] of the stretchable laminate is 0.14 (N/30 mm·gsm) or more.
