A disposable diaper (10) includes: an absorbing core a core wrap (40b) disposed on the skin-facing side of the absorbing core and a top sheet (50) disposed on the skin-facing side of the core wrap. The top sheet (50) includes low-weight sections (51) and high-weight sections (52). The low-weight sections and the high-weight sections extend in a longitudinal direction (L) and are alternately arranged in a width direction (W). The core wrap includes colored sections (80) that can be viewed from the skin-facing side of the absorbent article. The colored sections are disposed at a distance from each other in the longitudinal direction and are disposed at a distance from each other in the width direction. The widthwise length (L532) of the colored sections is shorter than the sum of the widthwise length (L512) of the low-weight sections and the widthwise length (L522) of the high-weight sections. The disposable diaper includes first regions (R1) where the colored sections and the low-weight sections overlap each other, and second regions (R2) where the colored sections and the high-weight sections overlap each other.用後即棄式紙尿布(10)具備:吸收芯、配置在吸收芯的肌膚對向面側的芯包層(40b)、以及配置在芯包層的肌膚對向面側的頂部薄片(50)。頂部薄片(50)具有低基重部(51)和高基重部(52)。低基重部和高基重部分別沿著長度方向(L)延伸,而在寬度方向(W)交替地配置。芯包層具有從吸收性物品的肌膚對向面側可辨識的著色部(80)。著色部在長度方向隔著間隔配置,且在寬度方向隔著間隔配置。著色部的寬度方向的長度(L532),短於低基重部的寬度方向的長度(L512)和高基重部的寬度方向的長度(L522)合計的合計長度。用後即棄式紙尿布具有:著色部和低基重部重疊的第1區域(R1)、及著色部和高基重部重疊的第2區域(R2)。51‧‧‧低基重部52‧‧‧高基重部R1‧‧‧第1區域R2‧‧‧第2區域R3‧‧‧第3區域R4‧‧‧第4區域80‧‧‧著色部L801‧‧‧長度L802‧‧‧長度D801‧‧‧間隔D802‧‧‧間隔D512‧‧‧間隔D522‧‧‧間隔L512‧‧‧長度L522‧‧‧長度P51‧‧‧長度L‧‧‧長度方向(第1方向)W‧‧‧寬度方向(第2方向)
