The stretchable sheet (4) is composed by having a base material sheet (41) sandwich multiple elastic stretchable members (42) disposed therein in an extended state, said multiple elastic stretchable members (42) being disposed along the width direction of the disposable diaper and spaced apart at intervals in the longitudinal direction. When viewed in the width direction, the stretchable sheet (4) has an overlapping portion (43) which includes a region that overlaps with a part of the absorber (3). In the overlapping portion (43), the multiple elastic stretchable members (42) are disposed continuously along the width direction. The multiple elastic stretchable members (42) are not joined to the sides of the base material sheet (41) at the central region (43a) of the overlapping portion (43), said central region (43) being where part of the absorber (3) is overlapped, and are joined to the sides of the base material sheet (41) at the side regions (43b) of the overlapping portion (43) which are positioned to the outside of the central region (43a) in the width direction.
