PROBLEM TO BE SOLVED: To provide a disposable underpants type wearing article which is formed by a relatively soft sheet material, whose proximal part is easily deformed, and which has a tape fastener stably attaching a distal part.SOLUTION: In a disposable underpants type wearing article, at least a first waist region 14 of back and forth waist regions 13, 14 has elasticity in a horizontal direction X, and a tape fastener 20 is formed by a fiber nonwoven fabric and includes a proximal part 21 which is fixed near a side part 18 of the first waist region 14 via a joint area 60 and a distal part 22 which has an engaging hook area 68 for engaging and hooking the tape fastener 20 with an outer surface of the second waist region 13. At least between the joint area 60 and the engaging hook area 68 of the distal part 22, a high rigidity area 70 whose rigidity in the direction in which both side edge parts of the tape fastener 20 approximate to each other is higher than that of the proximal part 21 is formed.COPYRIGHT: (C)2015,JPO&INPIT【課題】比較的に柔軟なシート材料から形成され、近位部が変形し易く、かつ、遠位部が安定的に止着されるテープファスナを有する使い捨てのパンツ型着用物品の提供。【解決手段】使い捨てのパンツ型着用物品は、前後ウエスト域13,14のうちの少なくとも第1ウエスト域14が横方向Xにおいて弾性を有しており、テープファスナ20が、繊維不織布から形成されており、第1ウエスト域14の側部18の近傍に接合域60を介して固定された近位部21と、テープファスナ20を第2ウエスト域13の外面に剥離可能に掛止めるための掛止め域68を有する遠位部22とを含む。遠位部22のうちの少なくとも接合域60と掛止め域68との間には、テープファスナ20の両側縁部どうしが近づく方向における剛性が近位部21よりも高い高剛性領域70が形成される。【選択図】図5
