In a disposable wearing article, a first waist region is elasticized and formed of an inner sheet and an outer sheet. The non-skin-facing side of the outer sheet is formed substantially over its entire area with a plurality of thermocompression-bonded spots regularly and intermittently arranged at predetermined intervals. The outer sheet has non-thermocompressed regions surrounded by a plurality of thermocompression-bonded spots. A fibrous layer lying at least on the outer surface of said outer sheet is formed of thermal adhesive crimped fibers which are bonded together by thermocompression-bonding treatment in the thermocompression-bonded spots. The outer sheet and the inner sheet are bonded to each other by adhesive applied on at least one of respective opposite surfaces thereof so that the crimped fibers in the non-thermocompressed regions may protrude outward in a thickness direction of the outer sheet as the inner sheet contracts in the direction of the transverse axis Q.本發明提供一種，在外面薄片使用捲縮纖維，以接著劑接合內外面薄片的方式，提昇外面薄片的膨鬆性與柔軟性，肌膚觸感佳且看起來討喜的用後即棄式紙尿布。解決手段，一種第1腰域(13)的全部或其腰開口附近的一部分具有伸縮性，由形成肌膚對向面的內面薄片(32)、與形成非肌膚對向面的外面薄片(30)所形成的穿著用物品，其中，在外面薄片(30)的外面的幾乎全域，許多的熱壓接部(20)分開所需尺寸並規則地被配置。外面薄片(30)具有：被許多的熱壓接部(20)圍繞所劃成的非熱壓接域(64)，位在外面薄片(30)中的至少其外面的纖維層由熱融接性的捲縮纖維(63)所形成，在熱壓接部(20)，捲縮纖維(63)彼此藉由熱壓接被接合，外面薄片(30)與內面薄片(32)經由被塗布在該等的對向面的接著劑(35)彼此接合，藉由內面薄片(32)朝橫軸Q的方向的收縮，非熱壓接域(64)的捲縮纖維(63)朝外面薄片(30)的厚度方向隆起。
