To provide an absorbent article capable of sufficiently reducing the widthwise length of an absorbent core and further increasing comfort during wearing. This absorbent article (10) has: a crotch area (S3) including the longitudinal center of the absorbent article； a front side area (S1) located closer to the front side than the crotch area； a rear side area (S2) located closer to the rear side than the crotch area； and an absorbent core (50) disposed at least in the crotch area. The absorbent core has a pair of side slits (52) extending in the longitudinal direction. The absorbent core has: a central area (RC) sandwiched between the side slits； and side regions (RS) located between the side slits and the outer edges of the absorbent core. The side slits each have a large width section (53) having a larger widthwise length than the widthwise length of the side area in the crotch area. The longitudinal center (53CL) of the large width section is located closer to the front side than the longitudinal center (10CL) of the absorbent article.[課題]提供一種可充分縮短吸收芯的寬邊方向的長度，而可進一步提升穿用時的舒適性的吸收性物品。[解決手段]吸收性物品(10)具有：包含長邊方向的中央的胯下域(S3)、較胯下域更位於前側的前側域(S1)、較胯下域更位於後側的後側域(S2)；以及至少配置在胯下域的吸收芯(50)。在吸收芯形成有朝長邊方向延伸的一對的側細縫(52)。吸收芯具有：由側細縫所挾持的中央區域(RC)、以及位在側細縫與吸收芯的外側緣之間的側區域(RS)。側細縫具有寬廣部(53)，該寬廣部在胯下域具有側區域的寬邊方向的長度以上的寬邊方向的長度。寬廣部的長邊方向的中心(53CL)較吸收性物品的長邊方向的中心(10CL)更位於前側。
