According to the present invention, one center folding line (CFL), which is formed by folding an absorbent article (1), is formed in a middle section (M) or a rear section (R). An absorbent body (4) in the rear section (R) positioned further to the rear in the vertical direction (X) than the center folding line (CFL) has a pair of rear slit regions (RSr, RSl) sandwiching a virtual vertical center line (CL) from both sides, the rear slit regions (RSr, RSl) having disposed therein rear slits (R1) that extend in the vertical direction (X). Each of the pair of rear slit regions (RSr, RSl) has only one rear slit (R1) disposed therein or has a plurality of rear slits (R1) distributed and disposed therein.本發明之吸收性物品於中間部(M)或後方部(R),形成有1條藉由吸收性物品(1)之摺疊而形成之中央摺疊線(CFL)。位於較中央摺疊線(CFL)更靠縱向(X)之後方之後方部(R)之吸收體(4)係隔著假想縱中心線(CL),於兩側具有一對配置有於縱向(X)上延伸之後方狹縫(R1)之後方狹縫區域(RSr、RSl)。於該等一對後方狹縫區域(RSr、RSl)分別配置有僅1條後方狹縫(R1)或分散配置有複數條後方狹縫(R1)。1‧‧‧經期衛生棉(衛生棉)2‧‧‧正面片材4‧‧‧吸收體5‧‧‧防漏翻邊形成用片材6‧‧‧外槽7‧‧‧內槽10‧‧‧吸收性本體10H‧‧‧後翼部10S‧‧‧側翼部10W‧‧‧翼部41‧‧‧中央吸收性片材42‧‧‧本體吸收性片材43‧‧‧中高部43b‧‧‧後端44‧‧‧標準吸收部51‧‧‧接合線70‧‧‧後端CFL‧‧‧中央摺疊線CL‧‧‧縱中心線(假想縱中心線)d7‧‧‧距離F‧‧‧前方部FFL‧‧‧前方摺疊線M‧‧‧中間部M1‧‧‧中央狹縫MS‧‧‧中央狹縫區域R‧‧‧後方部R1‧‧‧後方狹縫RFL‧‧‧後方摺疊線RS‧‧‧後方狹縫區域RSr、RS1‧‧‧後方狹縫區域X‧‧‧縱向Y‧‧‧橫向
