PROBLEM TO BE SOLVED: To provide a disposable diaper having a shape along a three-dimensional shape of a body of a wearer in a worn state.SOLUTION: A disposable diaper 1 comprises a liquid permeable layer 2, a liquid impermeable layer 3, and an absorber layer 4. At least in the absorber layer 4, the disposable diaper 1 comprises a first bending guide line 6 and a second bending guide line 7 having curved shapes which protrude from one side edge 5a and the other side edge 5b respectively toward a longitudinal axis LA. The first bending guide line 6 and the second bending guide line 7 have predetermined first base points 15a and 15b on a front end FE side, and predetermined second base points 16a and 16b on a rear end RE side, respectively. The first bending guide line 6 and the second bending guide line 7 are formed by compressing at least the absorber layer 4. The disposable diaper 1 has the absorber layer 4 between the one side edge 5a and the first bending guide line 6, between the first bending guide line 6 and the second bending guide line 7, and between the other side edge 5b and the second bending guide line 7.SELECTED DRAWING: Figure 3【課題】着用状態において、着用者の体の立体形状に沿う使い捨ておむつを提供すること。【解決手段】液透過性層２と、液不透過性層３と、吸収層４とを備える使い捨ておむつ１であって、使い捨ておむつ１が、少なくとも吸収層４に、一方の側縁５ａ及び他方の側縁５ｂから、それぞれ、長手軸線ＬＡに向かって突出する湾曲形状を有する、第１折曲誘導線６及び第２折曲誘導線７を備え、第１折曲誘導線６及び第２折曲誘導線７のそれぞれが、前端ＦＥ側の、所定の第１基点１５ａ及び１５ｂと、後端ＲＥ側の、所定の第２基点１６ａ及び１６ｂとを有し、第１折曲誘導線６及び第２折曲誘導線７が、少なくとも吸収層４を圧縮することにより形成され、そして使い捨ておむつ１が、一方の側縁５ａ及び第１折曲誘導線６の間と、第１折曲誘導線６及び第２折曲誘導線７の間と、他方の側縁５ｂ及び第２折曲誘導線７の間とに吸収層４を有することを特徴とする使い捨ておむつ１。【選択図】図３
