The present invention addresses the problem of providing a urine absorption pad folded in an expandable manner and provided with a liquid-permeable top sheet on which protrusions are formed, the urine absorption pad being able to maintain the form of the protrusions formed on a predetermined region (for example, the region that comes into contact with the crutch area of a wearer) on the top sheet. In order to solve said problem, multiple sections (40b, 40f, 40d, 40h, and 40e) of an absorption layer overlap with a first overlapping section (40a1) of a first section (40a) on the absorption layer, multiple sections (40c, 40g, 40d, 40i, and 40e) of the absorption layer overlap with a second overlapping section (40a2), and a through hole (5) which penetrates the absorption layer in the thickness direction is positioned on a non-overlapping part (40a3).本發明的課題係在於提供一種失禁墊,其係具備形成有凸部的透液性之頂面薄片且可展開地折疊的失禁墊,可維持形成在頂面薄片中之預定區域(例如供穿用者的陰部抵接之區域)的凸部之形態者,為了解決該課題,在吸收層的第1部分(40a)中之第1重疊部分(40a1)重疊吸收層的複數個部分(40b、40f、40d、40h及40e),在第2重疊部分(40a2)重疊吸收層的複數個部分(40c、40g、40d、40i及40e),並使朝厚度方向貫通吸收層的貫通孔(5)位於非重疊部(40a3)。1‧‧‧失禁墊2‧‧‧透液性的頂面薄片3‧‧‧不透液性的背面薄片6a、6b‧‧‧防漏側邊21‧‧‧肌膚抵接面41‧‧‧第1層42‧‧‧第2層51‧‧‧第1層的貫通孔52‧‧‧第2層的貫通孔210‧‧‧背脊溝構造(凹凸構造的一例)411‧‧‧第1重疊部分412‧‧‧第2重疊部分413、414‧‧‧第1層41的端緣部421、422‧‧‧第2層42的端緣部423、424‧‧‧第2層42的端緣部
