The annular waist band 2 includes a bonded part 21 formed by bonding both end parts in a longitudinal direction in a belt-like sheet member 22 that is long in one direction in the form of being pressed. The belt-like sheet member 22 has, on at least a part thereof, extension/contraction parts 23a and 23b which are stretchable along the longitudinal direction of the belt-like sheet member 22. In a worn state of the article 1, the annular waist band 2 and the absorbent body 3 are detachably fixed such that the bonded part 21 of the annular waist band 2 is exposed to a skin non-abutting surface side of the annular waist band 1, and is positioned in a width direction center area of an abdominal side part or a back side part in the absorbent body 3.COPYRIGHT: (C)2013,JPO&INPIT【課題】ウエストベルトに形成された接合部が着用者の肌に当たることに起因する装着感の低下を効果的に防止し得るパンツ型吸収性物品を提供すること。【解決手段】パンツ型吸収性物品1は、環状ウエストバンド2と吸収性本体3とを備え、該環状ウエストバンド2と該吸収性本体3とが着脱可能になっている。環状ウエストバンド2は、一方向に長い帯状シート部材22における長手方向両端部どうしを、その幅方向に沿って合掌状に接合して形成された接合部21を有する。帯状シート部材22は、該帯状シート部材22の長手方向に沿って伸縮性のある伸縮部23a,23bを少なくとも一部に有する。物品1の着用状態において、環状ウエストバンド2の接合部21が、該環状ウエストバンド1の非肌当接面側に露出し、かつ吸収性本体3における腹側部又は背側部の幅方向中央域に位置するように、環状ウエストバンド2と吸収性本体3とが着脱可能に固定される。【選択図】図1
