To provide a pad with which a thrice-folded state in a front-back direction is achieved for maintaining the shape of a large number of convexities protruding on a surface sheet that prevents a decrease in liquid diffusion performance. A solution is provided by: causing, in plan view, a left anterior section of an anterior section to extend further left than a left-side narrowing edge of a narrowest-width section of a narrowing section, and a right anterior section of the anterior section to extend further right than a right-side narrowing edge of the narrowest-width section of the narrowing section； causing, in plan view, a left posterior section of a posterior section to extend further left than the left-side narrowing edge of the narrowest-width section of the narrowing section, and a right posterior section of the posterior section to extend further right than a right-side narrowing edge of the narrowest-width section of the narrowing section； folding the left anterior section and left posterior section inward, centered on a first left-side fold line extending in the front-back direction that is provided in proximity to a left side of the left-side narrowing edge； and folding the right anterior section and right posterior section inward, centered on a first right-side fold line extending in the front-back direction that is provided in proximity to a right side of the left-side narrowing edge.本發明所欲解決的問題在於提供一種尿片，其作成在前後方向上折成三層的狀態，該狀態可維持在正面片上突出的多數個凸部的形狀，該凸部可防止液體的擴散性降低。作為解決上述問題的手段，可藉由下述尿片來解決：在俯視觀察時，前側部的左前側部比收攏部的最窄寬度部的左側收攏邊緣更向左側延伸，前側部的右前側部比收攏部的最窄寬度部的右側收攏邊緣更向右側延伸；在俯視觀察時，後側部的左後側部比收攏部的最窄寬度部的左側收攏邊緣更向左側延伸，後側部的右後側部比收攏部的最窄寬度部的右側收攏邊緣更向右側延伸，左前側部與左後側部是以設置成接近左側收攏邊緣的左側且在前後方向上延伸的第一左側彎折線為中心而向內側彎折，且右前側部與右後側部是以設置成接近右側收攏邊緣的右側且在前後方向上延伸的第一右側彎折線為中心而向內側彎折。
