  • the curved portion 53 of the rear leg-hole elastic member 5R is disposed so as not to overlap the absorber in the thickness direction.
  • the elongation rate of the curved portion 53 of the rear leg-hole elastic member 5R is higher than the elongation rate of the straight portion 52 of the rear leg-hole elastic member 5R.
  • the elongation ratio of the straight line portion is 1.2 to 1.6 times, and the elongation ratio of the curved line portion is 2.1 to 2.5 times.
  • the elongation rate in the present embodiment is the elongation rate in the stretched state where the disposable diaper is stretched. Further, the elongation rate can be measured, for example, by the following method.
  • the product is fixed with the elastic member extended, and the dimensions of the straight part (between both ends in the inner width direction) and the curved part (both ends of the inner width direction from the inside of the locking) are measured (this dimension is I) Do).
  • this dimension is I) Do.
  • the product is cut at the elastic member portion.
  • the dimension is measured with a non-stretched elastic member placed straight with a ruler (this dimension is designated II). The calculated value of I / II is taken as the expansion rate.
  • the stretched state is a state in which the rear leg elastic member 5R as the first elastic member and the front leg elastic member 5F as the second elastic member are extended.
  • the disposable diaper is formed into a predetermined cylinder. It is in a state of wearing.
  • the dimensions of the cylinder can be set as follows. First, an exterior body constituting a disposable diaper is prepared in a state where the front elastic member and the rear elastic member are not arranged. The distance between the side joint portions 11 at the front end portion of the exterior body in a state where the elastic member is not disposed is measured. The distance between the side joints 11 at the front end of the exterior body is L11. Moreover, the distance between the side junction parts 11 in the rear side edge part of the exterior body in the state where the elastic member is not arranged is measured. The distance between the side joints 11 at the rear end of the exterior body is L12. Further, the dimension in the front-rear direction of the front waistline region is measured, and this dimension is L13. The dimension in the front-rear direction of the rear waist area is measured, and this dimension is L14.
  • the distance L11 between the side joints 11 at the front end of the exterior body and the distance L12 between the side joints 11 at the rear end of the exterior body are summed, and the total length ⁇ 0.8 is calculated.
  • X be the calculated value.
  • the length of the outer periphery of the cylinder is X.
  • the axial length of the cylinder is set to L13 and L14 or more.
  • each member constituting the disposable diaper 1 described above for example, a material described in JP-A-2006-346439 may be used.
  • the pants-type disposable diaper has been described.
  • the present invention is not limited to this and may be a shorts-type napkin.
  • the rear leg elastic member has been described as the outer elastic member, but the outer elastic member in the present invention can be applied to other elastic members such as a waist elastic member.
  • an absorbent article that can be manufactured by a simple manufacturing process and that can make leg side gathers easy to start on the wearer side.
