PROBLEM TO BE SOLVED: To provide a disposable paper diaper including an outer sheet with excellent texture of a material without causing skin troubles, since a touch to the skin is excellent.SOLUTION: For a disposable paper diaper 1 including an outer sheet 20, a plurality of elastic stretch members 24 and 25 are disposed along a horizontal direction at an interval in a vertical direction between upper layer nonwoven fabric 20A and a lower layer nonwoven fabric 20B. Thermally bonding fibers 26 are interposed between the upper layer nonwoven fabric 20A and the lower layer nonwoven fabric 20B, and by heat-seal of the thermally bonding fibers 26, the elastic stretch members 24 and 25 are fixed between the upper layer nonwoven fabric 20A and the lower layer nonwoven fabric 20B. Thus, decline of flexibility and deterioration of skin touch are not caused by hardening of an adhesive. Since an adhesive is not applied to the upper layer nonwoven fabric 20A and the lower layer nonwoven fabric 20B, the texture of a material is improved.
