Each of the nonwoven fabrics 71 disposed so as to cover the side edge of the absorber 4 from the side edge on the leg portion 6 side of the diaper is folded above the diaper (the surface side of the topsheet) to form a free edge of the first three-dimensional guard. 74a, and further downward (absorber side) at a position of a predetermined length from the free edge 74a of the first three-dimensional guard.
To form a free edge 74b of the second three-dimensional guard. Then, two overlapping non-woven fabrics 71 positioned on the absorber 4 between the first three-dimensional guard 7a and the second three-dimensional guard 7b,
The bonding portion 70 is formed by being fixed to the topsheet. That is, both the first three-dimensional guard 7a and the second three-dimensional guard 7b have the joint 70 side as a base end, and the first three-dimensional guard 7a is formed by folding and laminating two layers of the nonwoven fabric 71. And the second three-dimensional guard 7b is
It is composed of a single layer of nonwoven fabric 71. The nonwoven fabric 71 is disposed so as to cover the side surface of the absorber 4 and the side edge of the leg portion 6 of the disposable diaper, and is fixed to the back sheet 3. Thereby, the elastic members 61, 6 of the leg portion 6 are formed.
1 is sandwiched and fixed between the back sheet 3 and the nonwoven fabric 71. In the back part B and the abdomen part A, as shown in FIGS. 1 and 3, the portion of the nonwoven fabric 71 where the first three-dimensional guard 7 a is formed in the crotch part C is folded in the entire surface sheet. 2 and a portion of the nonwoven fabric 71 where the second three-dimensional guard 7b is formed in the crotch portion C is fixed to the nonwoven fabric 71 located on the side edge side of the abdomen A and the back B. Thus, neither the first nor the second three-dimensional guard 7a, 7b is formed in the abdominal part A and the dorsal part B. That is, the first and second three-dimensional guards 7a and 7b do not have to be formed over the entire disposable diaper as long as they are formed at least in the crotch part C.

Since one surface is formed by arranging a nonwoven fabric which is hydrophilic and the other surface is hydrophobic, the bodily fluid leaking beyond the first three-dimensional guard 7a is removed between the first three-dimensional guard and the second three-dimensional guard. Since the side is hydrophilic, it can be adsorbed and held, and furthermore, urine can be gradually led to the absorber from between the fibers, so that it is more excellent in leak prevention. In addition, the nonwoven fabric 7
