Even if the project of the present invention ties up to what and provides the situation of user's carry out activity, movement etc., the body that can also follow wearer causes the absorbent commodity of uncomfortable anxiety without having. Means to solve project are that the 1st and the 2nd side edge part (17,18) of absorbent commodity (10) is respectively provided with towards the necking section (30) of extension on the inside of transverse direction X. Position the 1st side edge part (17) of what necking section (30) and the 2nd side edge part (18) of position what necking section (30) system in the transverse direction, locate what it is opposite to position, absorber (20) system has a pair of deformation inductdion portion (40) of extensions on the inside of from absorber both side edges (20c, 20d) towards transverse direction X. Deformation inductdion portion (40) system position of absorber (20) is on from the inner end of necking section (30) (34) towards the imaginary line (K1-K3) of the linearly extension of longitudinal centre line (P).本發明之課題係在於提供即使使用者進行活動、運動等之情況，也能追隨穿用者的身體而不會有造成不舒服之虞的吸收性物品。用以解決課題之手段為，吸收性物品(10)的第1及第2側緣部(17、18)分別具有朝橫方向X內側延伸之頸縮部(30)。位於第1側緣部(17)之頸縮部(30)與位於第2側緣部(18)之頸縮部(30)係在橫方向上，處於相對向的位置，吸收體(20)係具有從吸收體兩側緣(20c、20d)朝橫方向X內側延伸之一對變形誘導部(40)。吸收體(20)的變形誘導部(40)係位在從頸縮部(30)的內端(34)朝縱向中心線(P)呈直線狀延伸之假想線(K1-K3)上。
