The present invention to provide an absorbent article having a plurality of pleats on the inner surface side facing the wearers side, having a composite sheet having excellent fit and familiar with the skin of the wearer. Composite sheet 17, intermittently and elastic non-woven fabric with a 172 (WD) stretch direction in one direction, and non-stretchable non-woven fabric 171, and 171 non-stretchable non-woven fabric and the elastic nonwoven fabric 172 along the stretching direction at least It is formed with the junction 173 are joined, so as to extend along the direction crossing the stretching direction by the slack of the 171 non-stretchable nonwoven fabric in a non-extended position 172 the elastic nonwoven fabric and a non-junction 173 between the junction When provided with the folds 174 of the multiple is tilted to align in one of the contracting direction of the fold 174 in the non-stretched state, the folded front end portion of the folds 174 does not reach the fold adjacent.本発明は装着者側を向く内面側に複数の襞を有し、装着者の肌に馴染んでフィット性に優れる複合シートを有する吸収性物品を提供する。複合シート17は、少なくとも一方向に伸縮方向(WD)を有する伸縮性不織布172と、非伸縮性不織布171と、伸縮性不織布172と非伸縮性不織布171とが前記伸縮方向に沿って断続的に接合される接合部173と、接合部173間の非接合部であって伸縮性不織布172の非伸張状態における非伸縮性不織布171の弛みにより前記伸縮方向と交差する方向に沿うように形成される複数の襞174とを備え、前記非伸張状態において襞174を前記伸縮方向の一方に揃えて傾倒させた際に、当該襞174の折り返し先端部が、隣接する襞に到達しない。
