Abstract
The present invention is intended to improve the liquid diffusibility and fit of an absorber having a first slit extending in a front-back direction and second slits continuing laterally from the first slit to the side edges. The foregoing issue is solved by providing one first slit extending in the front-back direction in a width-direction intermediate portion of an absorber, providing second slits continuing from each of front end side and back end side of the first slit toward width-direction both sides to the side edges, and providing second slit elastic members to cross in the direction of continuance of the second slits and exert a contraction force in the direction of closing of the second slits.
Claims5
A disposable diaper, wherein
- an absorbent article includes an absorber,
- the absorber has a first slit formation region in a width-direction intermediate portion where one or more first slits extending in a front-back direction are provided at width-direction intervals,
- the absorber has second slits continuing from each of front end side and back end side of the first slit formation region toward width-direction both sides to side edges,
- the absorbent article has second slit elastic members comprising elastic members, wherein the elastic members are provided on a back surface of the absorber, the elastic members cross the second slits, extend in the front-back direction, and exert a contraction force in the front-back direction to close the second slits,
- a duplicate sheet including a fixation portion fixed to the absorber, is provided on the back surface of the absorber, and
- the elastic members are fixed between the duplicate sheet in the fixation portion.
