The present invention aims to provide a wearing article improved so that front and rear waist regions can be easily and normally engaged with each other. A front waist region 8 is provided along a pair of opposite side edges 11 with first fastening members 13, and a rear waist region 9 is provided along a pair of opposite side edges 12 with second fastening members 14 adapted to be engaged with the associated first fastening members 13. Each of the second fastening members 14 is formed with an uneven structure having a plurality of crests 17 extending in a transverse direction X and spaced one from another in a longitudinal direction Y. Even when the uneven structure formed by the uneven region 16 as the latter 16 contracts comes in contact and engagement with the first fastening member 13, a degree of engaging force between the uneven structure and the first fastening member 13 is extremely weak and the uneven structure can be easily disengaged from the first fastening member 13. The uneven structure may be unfolded in the longitudinal direction Y and put in close contact with the first fastening member 13 to achieve firm engagement over an area as large as possible between the flattened uneven structure and the first fastening member 13.
