To provide a pants-type absorbent article capable of easily tearing a side seal part with a weak seal region as a starting point and reducing labor and time when detaching from a wearer.In a pants-type absorbent article (1) of the present invention, a side seal part (4) has a weak seal region (42) sandwiched between upper and lower seal regions (41, 43) having high seal strength. An elastic member 24 extending in the circumferential direction of the tubular waistline portion D is disposed on the belly side portion A and the dorsal side portion B of the pants-type absorbent article 1, and elastic members having different thicknesses are provided on one or both sides Weak elongation stress regions D1, D3 and strongly elongation stress regions D2, D4 are formed. The strongly elongated stress regions D 2 and D 4 are located below the weakly elongated stress regions D 1 and D 3, and a part thereof is located within the height range S 2 corresponding to the weak sealed region 42 in the cylindrical waistline part D, The boundaries Da and Db between the elongation stress regions D 1 and D 3 and the strongly stretching stress regions D 2 and D 4 are located within the same height range S 2.(FIG.【課題】弱シール領域を起点にしてサイドシール部を容易に引き裂くことができ、着用者から取り外す際の手間や時間を削減可能なパンツ型吸収性物品を提供する。【解決手段】本考案のパンツ型吸収性物品1は、サイドシール部4が、シール強度が高いシール領域41,43に上下を挟まれた弱シール領域42を有している。パンツ型吸収性物品1の腹側部A及び背側部Bには、筒状胴回り部Dの周方向に延びる弾性部材24が配されており、一方又は双方に、太さの異なる弾性部材が配された弱伸長応力域D1,D3及び強伸長応力域D2,D4が形成されている。強伸長応力域D2,D4は、弱伸長応力域D1,D3より下方に位置し、それぞれの一部分が、筒状胴回り部Dにおける弱シール領域42に対応する高さ範囲S2内に位置し、弱伸長応力域D1,D3と強伸長応力域D2,D4との境界Da,Dbが同高さ範囲S2内に位置している。【選択図】図5
