A diaper having an improved conjugated structure that is convenient, low-cost and easy for mass production is disclosed. The diaper includes a side wing having a magic hook located thereon and a rear thin sheet having an anti-leaking layer and a non-textile fabrics layer conjugated entirely or partially. The conjugation strength between the magic hook and the rear thin sheet is about 100 to 700 g/inch at 180 degrees, and the shear stress at 180 degrees is over 1000 g/inch. With the conjugation between the magic hook and the rear thin sheet, the user can randomly attach the magic hook to the surface of the non-textile fabrics layer to adjust the tightness of the diaper.
