PROBLEM TO BE SOLVED: To prevent, in a more suitable manner, a fixing part from being turned up and detached from a fixed part.SOLUTION: A paper diaper 1 includes: a body part 10 having an abdomen side portion 11 and a back side portion 12 a pair of fixing parts 20, 20 extended to both sides of the back side portion 12 and a fixed part 30 provided on the outer surface of the abdomen side portion 11, to which the pair of fixing parts 20, 20 are fixed. The fixing part 20 includes: a base material 21 having one end joined to the back side portion 12 a plurality of elastic members 22 extended from the one end to the other end of the base material 21 and expanded/contracted in the width direction of the paper diaper 1, the elastic members being disposed in a direction orthogonal to the extended/contracted direction and a fastening member 23 fixed to the base material 21 on the free end side in the width direction of the absorptive article 1 beyond an elastic region 21A provided with the elastic members 22. The elastic region 21A is configured such that the elastic members 22 are disposed over the whole area in the orthogonal direction, and further both ends in the orthogonal direction are easily elongated in comparison with the center in the orthogonal direction.
