The present invention prevents the worsening of an appearance of folding caused by unintended adhesion. An expanding/contracting structure of an absorbent article, said expanding/contracting structure comprising: a first sheet layer (12S) that comprises a nonwoven fabric； a second sheet layer (12H) that comprises a nonwoven fabric and faces one surface of the first sheet layer (12S)； and a plurality of long, narrow elastic expanding/contracting members (19) that are provided between the first sheet layer (12S) and the second sheet layer (12H), along an expanding/contracting direction and with gaps between one another, wherein the first sheet layer (12S) and the second sheet layer (12H) have sheet bonding sections (70) that are bonded via a hot melt adhesive that is arranged intermittently in a lengthwise direction of the elastic expanding/contracting members (19), in a pattern of long, narrow stripes extending in a direction that intersects the elastic expanding/contracting members (19), one of the first sheet layer (12S) and the second sheet layer (12H) comprises a spunbond nonwoven fabric and the other comprises an air-through nonwoven fabric, and the air-through nonwoven fabric has a raised nap on a surface that is on the spunbond nonwoven fabric side thereof.本發明所要解決的問題在於提供一種吸收性物品的伸縮結構，其能夠防止因意外的黏合所導致的褶皺的外觀惡化。為了解決此問題，本發明的吸收性物品的伸縮結構，具備：第一片層12S，其由不織布所構成；第二片層12H，其由與此第一片層12S的其中一面相對向之不織布所構成；及，複數根細長狀的彈性伸縮構件19，其以沿著伸縮方向且互相隔開間隔的方式被設置在這些第一片層12S與第二片層12H之間；其中，第一片層12S和第二片層12H具有藉由熱熔黏合劑接合而成的片接合部70，該熱熔黏合劑以在彈性伸縮構件19的長度方向上為間歇性且在與彈性伸縮構件19交叉的方向上細長地連續的條紋狀圖案進行配置，並且，第一片層12S和第二片層12H的任一方是由紡絲黏合不織布所構成且另一方是由熱風不織布所構成，此熱風不織布的靠紡絲黏合不織布側的面被作成絨面。
