A fastening tape (100) provided to this disposable diaper (10) has a substrate sheet (120) and a hook sheet (110) affixed to the substrate sheet (120). The hook sheet (110) has: a base sheet section (115)； a plurality of engagement hooks (111) that stand at the obverse surface of the base sheet section (115)； and a plurality of anchors (112) protruding from the reverse surface of the base sheet section (115) to the substrate sheet (120). At least a portion of the anchors (112) are formed at a position overlapping the engagement hooks (111) in a plan view of the fastening tape (100).本發明的課題係在於提供既可將鉤薄片與基材薄片確實地接合，又可減低接觸到扣帶時的不舒適感之用後即棄式紙尿布及鉤薄片。設在用後即棄式紙尿布(10)的扣帶(100)係具有：基材薄片(120)；及固定在基材薄片(120)的鉤薄片(110)。鉤薄片(110)係具有：基材薄片部(115)；從基材薄片部(115)的表面立設的複數個卡合鉤(111)；及從基材薄片部(115)的裏面朝基材薄片(120)突出的複數個固定器(112)。固定器(112)的至少一部分係在扣帶(100)的平面視角，形成於與卡合鉤(111)重疊之位置。
