An absorbent product including a front surface sheet (2) which comprises nonwoven fabric (1) having a corrugated structure composed of ridges (13) and grooves (14) extending in the longitudinal direction and disposed alternately in the width direction Y. The front surface sheet (2) has been bonded to an adjoining lower sheet (6) at the grooves (14). The nonwoven fabric (1) was formed from at least high-elongation fibers as a raw material. The lower sheet (6) comprises a mass of thermoplastic resin fibers. The ridges (13) have a hollow structure. In the ridges (13), the lateral zones (14c) have a lower fiber density than both the top zones (13a) and the bottom zones (13b).正面片材(2)包含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交替地配置而成之凹凸構造之不織布(1)。正面片材(2)於凹條部(14),與鄰接之下側片材(6)接合。不織布(1)至少以高伸長率纖維作為原料。下側片材(6)包含熱塑性樹脂之纖維之集合體。凸條部(13)具有中空構造。凸條部(13)之側部區域(14c)之纖維密度較頂部區域(13a)之纖維密度及底部區域(13b)之纖維密度之任一者都低。1‧‧‧不織布2‧‧‧正面片材11‧‧‧纖維13‧‧‧凸條部14‧‧‧凹條部14s‧‧‧接合部H‧‧‧高度X‧‧‧長度方向Y‧‧‧寬度方向Z‧‧‧厚度方向
