Three or more elongated cover portion elastic members along a width direction are disposed in a gluteal cover portion of a back outer member. The gluteal cover portion is contracted in the width direction by the cover portion elastic members. The cover portion elastic member located closest to a waist opening is disposed at an end portion of the gluteal cover portion on the waist opening side. The cover portion elastic member located closest to a leg opening is disposed at an end portion of the gluteal cover portion on the leg opening side. When a central interval between the cover portion elastic member located closest to the waist opening and the cover portion elastic member located second from the waist opening is represented by d.sub.A, and the front-back direction length of the gluteal cover portion is represented by d.sub.E, d.sub.A>0.5d.sub.E is satisfied.

A disposable diaper whose deformation while the wearer is walking, is suppressed to alleviate discomfort, first slits extend from ventral section to the front of crotch section in their side portions at a distance from and in parallel to first oblique parts, a second slit extends in parallel to straight parts, in the central part in the width direction of middle area of the crotch section, third slits extend at a distance from second oblique parts in the back of the crotch section in its side portions, with the back end of each third slit located outwards of its front end, fourth slits extend crossing each other in parallel to the second oblique parts, in the middle area of dorsal section, back ends of the first slits are located inwards of the straight parts, and front ends of the fourth slits are at a longitudinal distance from the back ends of the third slits.

An absorbent article includes: an absorbent main, an abdominal-side band member having a central portion fixed to one end part in a vertical direction of the absorbent main body while covering the one end part from a non-skin side of the absorbent main body, and a back-side band member different from the abdominal-side band member. The back-side band member has a central portion fixed to an other end part in the vertical direction of the absorbent main body, while covering the other end part from the non-skin side of the absorbent main body. The back-side band member has a length in the vertical direction longer than the abdominal-side band member. Each of the abdominal-side and back-side band members has an elastic member. The abdominal-side band member and the absorbent main body overlap at an overlap portion, the overlap portion including at least a part where the elastic member is disconnected.

Wearable article comprising an elastic laminate with excellent sweat management properties. The elastic laminate comprises an inner first nonwoven layer and an outer second nonwoven layer. The outer layer has a higher hydrophilicity than the inner layer. The laminate has a total caliper when subjected to the NMR MOUSE method as described. The total caliper has a first sub-caliper corresponding to 50% of the total caliper, and a second sub-caliper corresponding to the remaining 50% of the total caliper. The elastic laminate has a Liquid Ratio of the first sub-caliper to the second sub-caliper of at least 1.1 after 1 minute according to the NMR MOUSE method.

An absorbent article including a main body with an absorbent core, and a ring-like elastic belt, is disclosed. The article may include a front belt and a back belt each formed by an inner sheet, an outer sheet and a plurality of elastic bodies sandwiched therebetween and running in the transverse direction. The elastic bodies in the back belt may include a plurality of waist elastic bodies having elasticity over the entire transverse width of the back belt; a plurality of tummy elastic bodies removed of their elasticity in at least a portion overlapping the absorbent core, and a core edge elastic body disposed overlapping the absorbent core and adjacent the distal edge of the absorbent core, the core edge elastic body having elasticity over the entire transverse width of the back belt.
