PROBLEM TO BE SOLVED: To provide a disposable diaper which increases absorbency with respect to urination and fitness in wearing, is less likely to cause misunderstanding of the occurrence of urination before the urination, and can improve the impression of the diaper from a side of a surface sheet after the urination.SOLUTION: A disposable diaper 1A disclosed in this invention has an indicator 9 between a rear surface sheet 3 and an absorber 4. A surface sheet 2 is two-layered. The absorber 4 has a non-fiber stacked part 42 in an absorbent core 40. In a cross-section view, the indicator 9 is overlapped with the non-fiber stacked part 42 in a thickness direction. When the diaper 1A is measured by a color-difference meter from a side of the surface sheet 2, a color difference ( Evalue) between a color of the surface sheet in a position of the absorbent core 40 and a color of the surface sheet in a position overlapped with the indicator 9 is 8 or less in the state of DRY. The color difference ( Evalue) between a color of the surface sheet 2 in a position overlapped with the indicator 9 in the state of WET and the color of the surface sheet 2 in the position overlapped with the indicator 9 in the state of DRY is 32 or less.SELECTED DRAWING: Figure 3 【課題】排尿に対する吸収性が向上し、着用時のフィット性が向上すると共に、排尿前に排尿したと勘違いされ難く、排尿後の表面シート側からのおむつの印象が改善できる使い捨ておむつを提供すること。【解決手段】本発明の使い捨ておむつ１Ａは、裏面シート３及び吸収体４の間にインジケーター９を有する。表面シート２は２層を有する。吸収体４は、吸収性コア４０に非積繊部４２を有する。断面視して、インジケーター９は厚さ方向にて非積繊部４２と重なる。おむつ１Ａを表面シート２側から色差計で測定した際、ＤＲＹ時、吸収性コア４０の位置での表面シートの色と、インジケーター９と重なる位置での表面シートの色とは、色差（ΔＥ＊値）が８以下である。ＷＥＴ時のインジケーター９と重なる位置での表面シート２の色と、ＤＲＹ時のインジケーター９と重なる位置での表面シート２の色とは、前記色差（ΔＥ＊値）が３２以下である。【選択図】図３
