The present invention provides an absorbent article for urine which can exhibit excellent absorption ability even when urine is repeatedly supplied by a wearer. This absorbent article for urine comprises a nonwoven fabric having an uneven structure of protruding ridges (21) and grooves (22) alternatingly arranged in a second direction which is perpendicular to a first direction, the protruding ridges (21) being protrusions, in the thickness direction, of a surface sheet (2) on the skin-facing side that extends in the first direction, and the grooves (22) being recessed, in the thickness direction, towards the non-skin-facing side and extending parallel to the protruding ridges (21) in the first direction. The nonwoven fabric has a grammage of 25 g/m2 to 50 g/m2 and a thickness of 0.7 mm to 2.0 mm. The surface sheet (2) has a high-density part having a relatively high fiber density in the grooves (22) and has, on the skin-facing side surface, a protein dispersion means for dispersing Tamm-Horsfall mucoprotein in urine.本發明，可以提供以尿為對象的吸收性物品，即使尿是從穿著者被反覆供給的情況也可以發揮良好的吸收性能的吸收性物品者。本發明的以尿為對象的吸收性物品，是具有使：表面薄片(2)在厚度方向朝肌膚相對面側突出且朝第1方向延伸的凸條部(21)、及在前述厚度方向朝非肌膚相對面側凹陷且與前述凸條部(21)並行地朝前述第1方向延伸的溝部(22)，沿著與前述第1方向垂直交叉的第2方向交互地配置的凹凸構造，並且由具有25g/m2～50g/m2的基重、及0.7mm～2.0mm的厚度的不織布所構成，進一步，前述表面薄片(2)，是在前述溝部(22)中具有纖維密度相對較高的高密度部，在肌膚相對面側的表面，具有將被包含於尿中的塔姆霍斯福爾黏膜蛋白質分散的蛋白質分散手段。
