PROBLEM TO BE SOLVED: To suppress wrinkles in a part from a non-connection part to a base end part of a connection tape.SOLUTION: A tape type disposable diaper is configured such that: a lower edge 84L of a non-connection part 84 of a connection tape 80 has a shape which is decreased from a distal end 84f far from a base end part 81 of the connection tape 80 to a proximal end 84n close to the base end part 81 without having a folding point and an inflection point； a tangent line angle θ of the distal end 84f of the lower edge 84L the non-connection part 84 is 80-85 degrees； a tangent line angle θ of the proximal end 84n of the lower edge 84L of the non-connection part 84 is 0 degree； and when making as r, a shorter distance in a distance in a width direction WD between the proximal end 84n of the lower edge 84L of the non-connection part 84 and the distal end 84f of the lower edge 84L of the non-connection part 84, and a distance in a backward and forward direction LD between the proximal end 84n of the lower edge 84L of the non-connection part 84 and the distal end 84f of the lower edge 84L of the non-connection part 84, the whole of the lower edge 84L of the non-connection part 84 comprises only a part having a curvature radius of 0.8r or more.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2020,JPO&INPIT【課題】連結テープの非連結部から基端部にかけての部分におけるシワを抑制する。【解決手段】上記課題は、連結テープ８０の非連結部８４の下縁８４Ｌは、連結テープ８０の基端部８１に遠い遠位端８４ｆから基端部８１に近い近位端８４ｎに向かって、屈曲点及び変曲点を有することなく減少する形状を有し、非連結部８４の下縁８４Ｌの遠位端８４ｆの接線角度θは８０～８５度であり、非連結部８４の下縁８４Ｌの近位端８４ｎの接線角度θは０度であり、非連結部８４の下縁８４Ｌの近位端８４ｎと非連結部８４の下縁８４Ｌの遠位端８４ｆとの幅方向ＷＤの距離、及び非連結部８４の下縁８４Ｌの近位端８４ｎと非連結部８４の下縁８４Ｌの遠位端８４ｆとの前後方向ＬＤの距離のうち、いずれか短い方の距離をｒとしたとき、非連結部８４の下縁８４Ｌの全体は、曲率半径が０．８ｒ以上の部分のみからなる、テープタイプ使い捨ておむつにより解決される。【選択図】図８
