る。SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. 4-109 is disclosed.
In the underpants-type diaper body described in Japanese Patent No. 943, the leg openings on both sides are cut off only at the middle part to form a leg opening, so that the waist is widely covered and the leg opening tightens the thigh root. Although it has a shape and a function to prevent excretion leakage, it has a narrow leg opening and a large number of parts that cover the body, so the range of applicable sizes to be targeted is narrow, and it tends to hinder exercise when worn. Also, since there are many parts covering the body, it is difficult to attach and detach the body, and furthermore, there are problems in that many materials are used and the material cost is increased.

収されなくなる問題がある。Further, in this disposable diaper, the waist belt is disposed on both sides of the liquid-impermeable back sheet, so that the waist belt does not touch the abdominal area and the back area of the skin, and the liquid-impermeable back sheet is not provided. The liquid-permeable surface sheet, which has a better touch than the sheet, is comfortable to wear, but the waist belt must be folded back when used. There is a problem that the liquid back sheet is located and the excreted liquid is not absorbed.

A diaper main body formed of a sealed liquid absorber and having leg gather portions having elastic bodies on both side leg portions in the width direction; and a diaper main body along both sides of the liquid-permeable topsheet along the longitudinal direction. And a waist belt having elastic bodies with both ends fastened to both end edges of the diaper main body, respectively, wherein both ends of the waist belt are provided at both longitudinal ends of the diaper main body in the width direction of the diaper main body. From the center side to the sides around the legs around and joined in an inclined shape,
The both leg portions of the diaper main body are formed by cutting out both side portions between the joining portions of the waist belts at both ends of the diaper main body, and the both leg leg portions of the diaper main body are formed in a longitudinal direction of the diaper main body. The front side from the substantially central portion is notched and formed in a substantially concave arc shape, and the length in the width direction of the waist belt on both sides disposed on both sides of the liquid-permeable surface sheet of the diaper body is the length in the width direction of the diaper body. forming a gap between both side waist belt as less than half of the said opposite sides rag
At both ends of the belt, both ends of the waist belt
The elastic body of the part and the elastic body of the leg gather part are integrated
So that both ends of the waist belt and the
Opposite both ends of the leg gather section,
One of the two ends that connects the belt
A concave arc is formed at the center of the edge, and the other end is formed.

力で皺が生じることがなく装着感が良好になる。The leg portions on both sides of the diaper main body are formed by cutting out both side portions between the joining portions of the waist belts at both ends of the diaper main body, so that the leg opening becomes large and the range of applicable sizes is widened. It is possible to enhance the mobility at the time of wearing. In addition, the leg portions on both sides of the diaper body are formed by notching the front side from a substantially central portion in the longitudinal direction of the diaper body in a substantially concave arc shape, so that the leg opening of the diaper body can strongly tighten the thigh root. No discomfort occurs in the abdomen and back when the diaper is worn. Furthermore, since a gap was formed between the waist belts on both sides of the diaper body, the elastic force of the waist belt did not directly act on the parts that touched the abdomen and back of the skin,
A feeling of oppression is not generated on the abdomen, and the diaper main body does not wrinkle due to the elasticity of the waist belt in a portion that touches the abdomen and the back, thereby improving the feeling of wearing.
