To improve the visual effect of holes when a perforated nonwoven fabric is used for a cover nonwoven fabric in an outer member separated-type underpants-type disposable diaper. To solve the above problem, a cover nonwoven fabric 13 that covers a back surface of an inner member 200 from between a front side outer member 12F and the inner member 200 to between a back side outer member 12B and the inner member 200 is included, in this cover nonwoven fabric 13, a large number of holes 14 which penetrate the front surface and back surface from between the front side outer member 12F and the inner member 200 to between the back side outer member 12B and the inner member 20 are provided at intervals, and the front side outer member 12F and the back side outer member 12B have, at least at portions overlapping with the cover nonwoven fabric and not having any elastic member, a total luminous transmittance of 50% or more.
