A pair of fastening members (8) are fixed to an absorbent main body (5) on the dorsal side portion (1R), and a non-fiber stacked portion (45) is formed extending in the longitudinal direction X in an absorbent core (40) in a crotch portion (1M). The fastening members (8) include an elastic side panel (6) fixed to the side edge portion (5S) of the absorbent main body (5) and a fastening tape (7). When a virtual straight line (L1) passing through a side panel fixing point (A) and a fastening tape fixing point (B) is drawn to each of the pair of fastening members (8) in the unfolded state of the absorbent main body (5) and the natural state of the side panels (6), the dorsal side longitudinal end (45R) of the non-fiber stacked portion (45) is positioned at or near the intersection (C) of the two virtual straight lines (L1), and the non-fiber stacked portion (45) extends in the longitudinal direction (X) from the dorsal side longitudinal end (45R) toward the ventral side longitudinal end (40F) of the absorbent core (40).本發明之吸收性物品係於背側部(1R)中之吸收性本體(5)固定有一對固定用構件(8)，於胯下部(1M)中之吸收性芯體(40)形成有沿縱向X延伸之非纖維堆積部(45)。固定用構件(8)包含固定於吸收性本體(5)之側緣部(5S)之伸縮性之側片(6)及黏扣帶(7)。於在吸收性本體(5)之展開狀態且側片(6)之自然狀態下，對一對固定用構件(8)各者拉出通過側片固定點(A)及黏扣帶固定點(B)之假想直線(L1)之情形時，非纖維堆積部(45)之背側縱向端(45R)位於該2條假想直線(L1)之交點(C)或其附近，且非纖維堆積部(45)自背側縱向端(45R)朝向吸收性芯體(40)之腹側縱向端(40F)沿縱向(X)延伸。
