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.【課題】単純な製作方法によって作り出され、費用のかからないおむつやパンツ等に使い捨ての吸収性物品に用いる伸縮性積層体の提供。【解決手段】伸縮性積層体は、エラストマーフィルムを含む表面を有する第１層を含み、さらに第１層の両表面に取り付けられた表面を有する不織布材料を含む第２層および第３層を含んでいる。伸縮性積層体の横断方向の引張挙動は、工学ひずみ約１．５におけるフィルムの横断方向の引張挙動である約２．５Ｎ／ｃｍ以内で、機械的活性化とは無関係に存在する。前記第２及び第３層の少なくとも１つが、スパンボンド・メルトブロウン、スパンボンド・メルトブロウン・スパンボンド、及びスパンボンド・メルトブロウン・メルトブロウン・スパンボンド不織布から選択される不織布材料である伸縮性積層体。【選択図】なし
