Provided is a urine collection pad capable of absorbing urine up to almost the capacity of an absorbent body while preventing the absorbent body from disintegrating. This urine collection pad is provided with a front surface sheet (120), a back surface sheet (130) and an absorbent body (140). The absorbent body is provided with an upper absorbent body layer (140a) located on the skin side and a lower absorbent body layer (140b) located on the non-skin side. The upper absorbent body layer has an upper layer groove part (141a) in a urine excretion region, the upper layer groove part stretching in the longitudinal direction and extending from the front surface sheet side surface to the inside of the upper absorbent body layer in the thickness direction. The lower absorbent body layer comprises an absorbent core (144) and a cover sheet (145) wrapping the absorbent core. The cover sheet encloses the absorbent core in such a manner as to cover the non-skin side surface and both side surfaces in the width direction of the absorbent core and cover the skin side surface of the absorbent core in a state in which two edges in the width direction of the cover sheet overlap each other on the skin side of the absorbent core. The skin side surface of the absorbent core is not bonded to the cover sheet.本發明提供一種邊防止吸收體走樣的事態,又可吸收尿到接近吸收體所容許的容量為止的吸尿墊片。吸尿墊片,是具備表面薄片(120)與裏面薄片(130)和吸收體(140)。吸收體具備:位在肌膚側的上層吸收體(140a)、以及位在非肌膚側的下層吸收體(140b)。上層吸收體,是在排尿區域具有延伸設置在長邊方向,從表面薄片側的面朝厚度方向延伸到上層吸收體的內部的上層溝部(141a)。下層吸收體包含:吸收性芯(144)、以及包裹吸收性芯的被覆薄片(145)。被覆薄片,是覆蓋吸收性芯的非肌膚側的面及寬邊方向的兩側面,且以被覆薄片的寬邊方向的兩端緣彼此在吸收性芯的肌膚側疊合的狀態下覆蓋吸收性芯的肌膚側的面而包住吸收性芯。吸收性芯的肌膚側的面與被覆薄片非接合。121‧‧‧肌膚側表面120‧‧‧表面薄片124‧‧‧脊溝構造140‧‧‧吸收體140a‧‧‧上層吸收體140b‧‧‧下層吸收體140c‧‧‧上層薄片141a‧‧‧上層溝部141b‧‧‧下層吸收體144‧‧‧吸收性芯145‧‧‧被覆薄片130‧‧‧裏面薄片T‧‧‧厚度方向W‧‧‧寬邊方向L‧‧‧長邊方向
