Abstract: To prevent a paper diaper reliably from slipping down at a body liquid absorbing time, and to bring the paper diaper into close contact along the line of a body thereby to improve the wearing comfortableness. An armoring sheet includes: waist portion elastic members, and so on; hip surrounding elastic member groups, and so on arranged at the front F and the back B; and a plurality of curved elastic member groups extending, at each of the front F and the back B, from one side jointing edge to the crotch side, reaching the other side jointing edge while passing over the crotch side, and arranged at a spacing without intersecting with each other. The curved elastic member groups have their starting/trailing ends connected at a predetermined spacing substantially over the range from the upper portion to the lower portion of the side portion jointing edge.

Abstract: An outer packaging sheet in a paper diaper is provided with: hip elastic bands including a plurality of hip elastic members arranged from one joint end portion individually at a front and at a back to the other joint end portion; curved elastic bands including a plurality of curved elastic members extending from one of the joint end portions individually at the front and at the back to the side of a crotch portion and arranged over the other joint end portion while bypassing that crotch portion; and an absorbent body arranged in the crotch portion. The curved elastic bands are formed to cover such areas of the outer packaging sheet substantially as are enclosed by the edge portions of the outer packaging sheet, the absorbent body and the hip elastic bands.
