An absorbent article that can more secure the absorption area of the body fluid on the buttocks side during wear is provided. The absorbent article (10) has a front-rear direction (L), a width direction (W) perpendicularly intersecting the front-rear direction, a front-forward region (S1), and a rear-surrounding region (S2), and is disposed. The sub-femoral domain (S3) between the surrounding area of the anterior and posterior and the surrounding area of the posterior iliac crest, and the absorbent core (51) located at least in the sub-femoral domain. The fold line (FL) for folding the absorbent article in the width direction is in the lower strand field. The high-rigidity field (HR) is a field that is disposed on the rear side of the fold line and includes the center in the width direction. The high rigidity field is constituted by a field having a rigidity higher than that of a field between a fold line (FL) and a high rigidity field (HR). The length of the high rigidity region (HR) in the front-rear direction is longer than the length (L1) from the fold line to the front end edge of the high rigidity region.提供可以更確保穿著中的臀部側的體液的吸收面積的吸收性物品。吸收性物品(10)，是具有：前後方向(L)、及與前後方向垂直交叉的寬度方向(W)、及前胴周圍域(S1)、及後胴周圍域(S2)、及被配置於前胴周圍域及後胴周圍域之間的股下域(S3)、及至少設於股下域的吸收芯(51)。將吸收性物品對折用的折線(FL)，是在股下域沿著寬度方向延伸。高剛性領域(HR)，是被設置在比折線更後側且包含寬度方向的中心的領域。高剛性領域，是藉由具有剛性比折線(FL)及高剛性領域(HR)之間的領域的剛性更高的領域而構成。前後方向的高剛性領域(HR)的長度，是比從折線至高剛性領域的前端緣為止的長度(L1)更長。
