Provided is a body fluid-absorbing article for wearing, that is capable of stretching and shrinking. The body fluid-absorbing article for wearing, one example thereof being a sanitary napkin (10), has a top sheet (11), a back sheet (12), and an absorbent body (13) interposed between these sheets (11, 12). The top sheet (11) and the back sheet (12) have stretching properties in the longitudinal direction (A) thereof. At least one of these sheets (11, 12) is formed from: a first sheet (25) exhibiting stretching properties as a result of a plurality of pleats (28) that extend in the horizontal direction (B), being spread out in the longitudinal direction (A) and a second sheet (26) being elastically stretchable in the longitudinal direction (A), joining the first sheet (25) in an elastically relaxed state, and being interposed between the first sheet (25) and the absorbent body (13).為了提供能伸展和收縮的體液吸收性穿著用物品。以生理用衛生棉(10)作為一例之體液吸收性穿著用物品,具有:表面薄片層(11)、背面薄片層(12)、以及介在該等薄片層(11)、(12)之間的吸收體(13)。表面薄片層(11)和背面薄片層(12)具有朝縱向(A)的伸展性。該等薄片層(11)、(12)當中的至少一方之薄片層係由第1薄片(25)和第2薄片(26)形成,該第1薄片(25)係使朝横向(B)延伸的複數條褶襉(28)朝縱向(A)擴幅而展現伸展性,該第2薄片(26)可沿縱向(A)彈性地伸展和收縮,以彈性地鬆弛之狀態與第1薄片(25)接合且介在第1薄片(25)和吸收體(13)之間。10‧‧‧體液吸收性穿著用物品(生理用衛生棉)11‧‧‧表面薄片層11a‧‧‧肌膚對向面12‧‧‧背面薄片層13‧‧‧吸收體16‧‧‧側部17‧‧‧兩端部18‧‧‧周緣部19‧‧‧壓搾部21‧‧‧周緣22‧‧‧接著劑33‧‧‧分隔部位P‧‧‧中心線
