To provide an underpants type absorbent article having a waist member with high durability in an upper side part and excellent touch in a lower side part.SOLUTION: In an underpants type absorbent article (1), a front side waist part (FA) and a rear side waist part (BA) are joined by a pair of side joining parts (40, 40). A waist member (20) includes a plurality of elastic members (25) expanding and contracting in a right-and-left direction. A vertical position in each of the elastic members (25) is restricted by sandwiching between two vertically adjacent welding parts (50). A total amount of an area of the welding parts (50) provided in an upper side (FA1) of an intermediate position (FAC) in the vertical direction of the side joining part (40) in a region between the pair of the side joining parts (40, 40) in a right-and-left direction and between an upper end and a lower end of the side joining part (40) in the vertical direction is larger than a total amount of an area of the welding part (50) provided in a lower side (FA2).SELECTED DRAWING: Figure 8 【課題】上側部分では耐久性が高く、下側部分では肌触りが良好な胴回り部材を備えたパンツ型吸収性物品を提供する。【解決手段】前側胴回り部（ＦＡ）と後側胴回り部（ＢＡ）とが一対のサイド接合部（４０，４０）によって接合されたパンツ型吸収性物品（１）であって、胴回り部材（２０）は、左右方向に伸縮可能な弾性部材（２５）を複数備え、各々の弾性部材（２５）は、上下方向に隣り合う２つの溶着部（５０）の間に挟み込まれることにより、上下方向の位置が規制されており、左右方向における一対のサイド接合部（４０，４０）の間且つ上下方向におけるサイド接合部（４０）の上端と下端との間の領域で、サイド接合部（４０）の上下方向における中間位置（ＦＡＣ）よりも上側（ＦＡ１）に設けられた溶着部（５０）の合計の面積は、下側（ＦＡ２）に設けられた溶着部（５０）の合計の面積よりも大きい。【選択図】図８
