ある。The elastic member 4 of the leg opening is composed of a first member 4A and a second member 4B, each of which has a plurality of juxtaposed lines. The elastic strength of the first member 4A is larger than that of the second member 4B. To increase the stretch elastic strength, for example,
In the case where the member 4A has the same material, number, and cross-sectional area as the second member 4B, the amount of tension of the former may be larger than that of the latter,
Further, the material, number and cross-sectional area of the former and the latter may be different. The first and second members 4A and 4B have portions near both ends which are allowed to make a tolerance near the center of the recessed edges 13 and 14 for forming leg circumferences, and portions 4A 1 and 4B 1 extending from the tolerance portion to the outer end. And / or adhesive along the recessed edges 13 and 14 with an adhesive 17 applied to the inner surface of the back sheet, and without fixing the central portions 4A 2 and 4B 2 to any members, the top and back sheets 6 , 7 are located on the lower surface of the central area of the core 8 interposed in the central area. However, the center portions 4A 2 and 4B 2 can also be fixed to the back sheet with an adhesive. The elastic member 5 in the opening is adhered to the inner surface of the top and / or back sheet along the waist 16 with an adhesive (not shown).
