で着用物品とする技術が考えられる。The above-mentioned belt-like wearing article is made so that its width can cover about half of the circumference of the waist, and when worn, a large number of crotch portions are relatively narrow. Wrinkles occur and the feeling of wearing is poor. Wearing articles having notches for leg circumference can improve the wearing feeling, but when it is a diaper, despite excretion of body fluid being concentrated in the crotch region. The width of the liquid-absorbent core in this region is narrowed by the notch, and the amount of liquid absorption is reduced, which is one of the causes of body fluid leakage from the crotch region. On the other hand, in order to realize a good wearing feeling in the crotch region and a high liquid absorption amount at the same time, the front and rear bodies are formed separately, and each body is extended downward from the trunk covering portion and the covering portion. On the other hand, a wearable article is formed by arranging the liquid-absorbent core in the trunk covering portion and the leg covering portion while being constituted by the leg covering portion, and joining these front and rear bodies with a seal line that is convexly curved in the waist circumference direction in the crotch region. The following technology can be considered.

When 1 is cut out and the elastic member 55 under extension is cut at the same time, the non-bonded portion 74 is divided into two parts, and the bonded portions 71 and 7 are separated.
Each contracts to the 2 side. At this time, the width of the joint portion 57 is set so that the cut end portion 55B on the front body 2 side can be pulled out from the joint portion 57 and contracted inward. When the elastic member 55 is joined at the joining portion 57 and there is a possibility that the shrinkage does not occur, the joining portion 57 is provided so as to avoid the elastic member 55, and the avoided portion is locally heat-sealed by the heat seal line 75. Alternatively, the elastic member 55 may be cut before the second continuous web 50 is supplied. It is generally difficult to join the front and back sheets 30, 31 in a watertight manner around the elastic member 55, and voids are likely to be formed along the elastic member 55. If the elastic member 55 faces the outside of the diaper at the peripheral edge 63, the liquid-absorbent core 3 travels through such a gap.
The exudate of 2 may leak out. However, as shown in FIG. 4, if the end portion 55B of the elastic member contracts and the peripheral edge of the diaper 1 is reliably sealed by the joint portions 57 and 75, there is no risk of leakage. Also for the waist elastic member 54,
As with the leg elastic members 55, it is possible to provide a non-adhesive portion at the peripheral edge 63.
