Fitting characteristic to the wearing person is high, offer of the absorptive goods and the production method at the same time the position gap of the absorption structure being controlled. The absorptive goods of this invention are installed and with the 1st elastic member 6 which extending appears in the both sides of absorption structure 2 rectilinear in the chassis and the chassis where absorption structure 2 and absorption structure 2 is connected crossing the absorption structure territory 4 in body intersection direction, under expanding include. As the chassis is non expansion characteristic substantially, expansion ratio of 1st elastic member 6, it is low the absorption structure territory in each 1st side territory 5a which, it adjoins to 4 and the absorption structure territory 4 outside both sides alienates from each 1st side territory 5a to each side edge 15 of the chassis, while maintaining the expansion ratio which is higher than the 1st side territory 5a it changes continually. Regarding the production method of the absorptive goods, changing the supply speed of 1st elastic member 6 to the chassis which is supplied at one constant speed, periodically, while changing expansion ratio periodically, supplying, it connects to the chassis.着用者へのフィット性が高く、かつ吸収構造体の位置ずれが抑制された吸収性物品と、その製造方法の提供。この発明の吸収性物品は、吸収構造体2と、吸収構造体2が接合されるシャーシと、シャーシに吸収構造体領域4を身体横断方向に横断して伸長下で取り付けられ吸収構造体2の両側に直線的に延出する第1弾性部材6とを含む。シャーシは実質的に非伸長性であり、第1弾性部材6の伸長率は、吸収構造体領域4および吸収構造体領域4の両側外方に隣接する各第1側領域5aにおいて低く、各第1側領域5aからシャーシの各側縁15へ離間するに従い、第1側領域5aより高い伸長率を維持しつつ連続的に変化する。吸収性物品の製造方法においては、一定速度で供給されるシャーシに、第1弾性部材6の供給速度を周期的に変化させて伸長率を周期的に変化させながら供給して、シャーシに接合する。
