Abstract: Provided is a stretchable laminate including an elastomer layer and a non-woven fabric layer arranged on at least one side of the elastomer layer, in which interlayer delamination does not occur between the elastomer layer and the non-woven fabric layer even when a load is applied onto a surface, on which the elastomer layer and the non-woven fabric layer are bonded onto each other, in a substantially perpendicular direction. Also provided is an article including such stretchable laminate. The stretchable laminate of the present invention includes: an elastomer layer; and a non-woven fabric layer arranged on at least one side of the elastomer layer, the stretchable laminate further including a hot-melt pressure-sensitive adhesive between the elastomer layer and the non-woven fabric layer, the hot-melt pressure-sensitive adhesive containing an olefin component.
