An absorbent article 1 having an absorbent pad 4 longer in the front-to-rear direction while worn. The absorbent pad 4 has, in a part in its longitudinal direction, a multi-layered portion M having more layers than other portion. The absorbent pad 4 has grooves 7A and 7B in each side portion thereof. With imaginary line X-X drawn straight across the absorbent pad 4 at the rear end Ma of the portion M, the grooves 7A and 7B extend between a point in front of the imaginary line X-X and a point at least 15 mm rearward from the imaginary line X-X. When the absorbent article 1 is viewed from the front to the rear, the number of the groove (s) 7 on each side portion of the absorbent pad 4 does not increase in a region of from the imaginary line X-X to a position 15 mm rearward of the imaginary line X-X.本發明之吸收性物品1係具備其長度方向與使用時的前後方向相同的吸收體4。前述吸收體4係於長度方向上的一部份具有層數比其他部份多的多層部M,且假設以假想直線X-X將吸收體4於多層部M的後端位置Ma沿寬度方向橫切時,於吸收體4的兩側部分別形成有跨越假想直線X-X的前後且由該假想直線X-X朝後方延伸15 mm以上的溝7A、7B。又,由前方朝後方看吸收性物品1時,形成於吸收體4的兩側部的溝7的數量,於假想直線X-X與由該假想直線X-X朝後方延伸15 mm後的位置之間並未增加。1...生理用衛生棉(吸收性物品)2...正面片體4...吸收體41...主吸收體42...補助吸收體5...側部片體61...主翼部61a...後端位置62...後部襟翼7...溝7A...溝7B...溝7C...連結部7D...連結部A...排泄部相對部B...前方部C...後方部CL...長度方向中央線M...多層部Ma...後端位置
