EACH OF FIRST FASTENING TAPES (411) AND SECOND FASTENING TAPES (412) PROVIDED ON BOTH LEFT AND RIGHT SIDES OF A DISPOSABLE DIAPER (1) HAS A FIRST FASTENING PART AND A SECOND FASTENING PART WHICH ARE AWAY FROM EACH OTHER. WHEN PUTTING THE DISPOSABLE DIAPER ON A SLENDER WEARER, THE SECOND FASTENING TAPE IS FASTENED ON AN ATTACHMENT PART OF MAIN BODY (2) PART SO AS TO BE LAID OVER THE FIRST FASTENING TAPE. IN THE SECOND FASTENING TAPE, SINCE AN INTERMEDIATE AREA IS PROVIDED BETWEEN THE FIRST FASTENING PART AND THE SECOND FASTENING PART, A TOTAL AREA OF FASTENING PARTS CAN BE REDUCED. SINCE A DISTANCE BETWEEN AN OUTER EDGE (4111) OF THE FIRST FASTENING PART AND AN INNER EDGE (4122) OF THE SECOND FASTENING PART IS MADE LARGER THAN A WIDTH OF A TAPE BASE AT THE INTERMEDIATE AREA IN THE FIRST FASTENING TAPE, THE SECOND FASTENING TAPE CAN BE EASILY FASTENED. (FIG. 6)
