PROBLEM TO BE SOLVED: To provide an elastic laminate which is elastically extensible in at least one direction.SOLUTION: An elastic laminate includes: an elastomeric material having a first surface and a second surface opposing the first surface; and a first nonwoven layer joined to the first surface of the elastomeric material. The first nonwoven layer is formed of component fibers having a primary fiber direction. The first nonwoven layer has a fiber orientation ratio within about ±20 degrees from the primary fiber direction of at least about 65%. The present invention is also directed to a disposable garment employing such an elastic laminate. 【課題】本発明は少なくとも１方向に弾性的に伸長性である弾性ラミネートを提供する。【解決手段】弾性ラミネートは、第１の表面および第１の表面の反対側の第２の表面を有するエラストマー材料およびエラストマー材料の第１の表面に結合する第１の不織布層を含む。第１の不織布層は、主たる繊維方向を有する成分繊維から形成されている。第１の不織布層は、少なくとも約６５％の主たる繊維方向から?約２０度の範囲の繊維配向比を有する。本発明はまた、そのような弾性ラミネートを用いる使い捨て着衣にも関する。【選択図】なし
