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 bypassing 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. Moreover, the curved elastic member groups, as arranged on the side of the front F, are given the arrangement pattern, in which the intersection angle on the acute side with the side edge of the absorbent body is 30 degrees or less, and the curved elastic member groups, as arranged on the side of the front B, are given the arrangement pattern, in which the intersection angle on the acute side with the side edge of the absorbent body is 35 degrees or more.
