PROBLEM TO BE SOLVED: To provide a stretch laminate which is produced with a simple production method, and which is used for a throwaway absorbent article requiring no expenses such as a diaper, a pant, or the like.SOLUTION: A stretch laminate includes a first layer including an elastomer film and having surfaces, and further includes a second layer and a third layer each including a nonwoven material and each having a surface which is attached to each of both surfaces of the first layer. The tensile behavior in the transverse direction of the stretch laminate is within about 2.5 N/cm of the tensile behavior in the transverse direction of the film at an engineering strain of about 1.5, and exists independent of mechanical activation. In the stretch laminate, at least one of the second layer and the third layer is composed of the nonwoven material selected from nonwoven fabrics of spunbond-meltblown, of spunbond-meltblown-spunbond, and of spunbond-meltblown-meltblown-spunbond. |
