PROBLEM TO BE SOLVED: To improve diffusivity while preventing occurrences of twist and cleft of an absorber and decrease in an amount of absorption.SOLUTION: The disposable diaper is characterized in that a coating area rate of at least one of a top-sheet hot-melt adhesive 31 for sticking a top sheet 30 to a back-side member thereof, an intermediate-sheet hot-melt adhesive 41 for sticking an intermediate sheet 40 to a back-side member thereof, and a wrapper-sheet hot-melt adhesive 51 for sticking a wrapper sheet 58 to a surface of an absorber 56 is set higher than that of a peripheral area thereof in a diffusion-promoted area 70 including an urination port position 71 and being inward separated from an inner peripheral edge of the absorber 56.SELECTED DRAWING: Figure 9 |
