This absorbent article is equipped with a liquid-permeable surface sheet (2) that constitutes the surface that comes into contact with the skin, a rear surface sheet (3), and an absorbent body (4) interposed between the two sheets. The absorbent article has a longitudinal direction (X) and a width direction (Y), and the surface sheet (2) is made from a nonwoven fabric (1) that has protruding ridges (13) and recessed grooves (14) that extend in the longitudinal direction and are positioned alternately in the width direction (Y). The recessed grooves (14) are joined with the adjoining underside sheet (6), and hollow structures are formed between the protruding ridges (13) and the underside sheet (6). The nonwoven fabric (1) contains fibers having a large-diameter part (17) and small diameter part (16) having fiber diameters that differ from one another, and the absorbent body (4) has highly flexible regions (5) having a lower bending stiffness than other parts, in a plurality of locations in the width direction.本發明之吸收性物品具備形成肌膚抵接面之液體透過性之正面片材(2)、背面片材(3)及介置於該等兩片材間之吸收體(4),且具有長度方向(X)及寬度方向(Y),正面片材(2)包括由沿長度方向延伸之條紋狀之凸條部(13)及凹條部(14)於寬度方向(Y)交替地配置之凹凸構造之不織布(1),且於凹條部(13)與鄰接之下側片材(6)接合,凸條部(13)於與下側片材(6)之間具有中空構造。不織布(1)包含具有纖維直徑互不相同之大徑部及小徑部之纖維,吸收體(4)於寬度方向上之複數個部位具有撓曲剛性較其他部分低之高可撓性區域(5)。1‧‧‧不織布2‧‧‧正面片材3‧‧‧背面片材4‧‧‧吸收體5‧‧‧高可撓性區域5a‧‧‧高可撓性區域5b‧‧‧高可撓性區域6‧‧‧下側片材7‧‧‧側翼8‧‧‧防漏翻邊8a‧‧‧自由端8b‧‧‧固定區域8c‧‧‧彈性構件8d‧‧‧面狀彈性區域10‧‧‧失禁護墊13‧‧‧凸條部14‧‧‧凹條部40‧‧‧吸收性芯體41‧‧‧包芯片材43‧‧‧壓縮部H‧‧‧高度L1‧‧‧直線L2‧‧‧直線L3‧‧‧間隔P‧‧‧間距R‧‧‧壓縮部行X‧‧‧長度方向Y‧‧‧寬度方向
