To suppress winkling in a portion extending from a non-connected section to a base end section of a connection tape. The problem is solved by a tape-type disposable diaper in which: a lower edge 84L of a non-connected section 84 of a connection tape 80 has a shape in which a tangent line angle [theta] decreases without bent points or inflection points from a distal end 84f far away from a base end section 81 of the connection tape 80 toward a proximal end 84n near the base end section 81, the tangential line angle [theta] of the lower edge 84L of the non-connected section 84 is 80-85 degrees at the distal end 84f and 0 degrees at the proximal end 84n, and the entirety of the lower edge 84L of the non-connected section 84 consists entirely of portions having a curvature of radius of at least 0.8r, where r is the shorter of the distance in the width direction WD between the proximal end 84n and distal end 84f of the lower edge 84L of the non-connected section 84, and the distance in the front-rear direction LD between the proximal end 84n and distal end 84f of the lower edge 84L of the non-connected section 84.本發明所要解決的問題在於提供一種黏貼型拋棄式尿布，其抑制在連結帶的自非連結部直到基端部的部分的皺褶。為了解決此問題，本發明的黏貼型拋棄式尿布，其連結帶80的非連結部84的下緣84L具有下述形狀，該形狀是切線角度隨著自連結帶80的遠離基端部81的遠位端84f朝向靠近基端部81的近位端84n而不具有回折點和反曲點地減少的形狀，非連結部84的下緣84L的遠位端84f的切線角度θ為80～85度，非連結部84的下緣84L的近位端84n的切線角度θ為0度，當將非連結部84的下緣84L的近位端84n與非連結部84的下緣84L的遠位端84f的寬度方向WD的距離、及非連結部84的下緣84L的近位端84n與非連結部84的下緣84L的遠位端84f的前後方向LD的距離中的較短的距離設為r時，非連結部84的下緣84L的整體均由曲率半徑為0.8r以上的部分所構成。
