Close contact with buttock cleavage is improved and leakage to the rear is prevented. Intermittent recess grooves 20 and 20 are formed in the longitudinal direction of a sanitary napkin 1 on a skin non-contact surface side of an absorbing body 4, a plurality of laterally long peripheral embosses 21, 21 ... are formed at intervals in the longitudinal direction of the sanitary napkin 1 on the absorbing body 4 located in the periphery of the recess groove 20, and an absorbing-body deficit portion 22 is formed at least between the recess grooves 20 and 20. Deformation in the transverse direction of the absorbing body 4 in the peripheral part is regulated by the peripheral embosses 21, 21 ..., deformation performance in the napkin width direction can be ensured by using a formed row of the recess grooves 20 and 20 as a flexible shaft, and deformation in a compression direction or a tension direction of the absorbing body 4 is absorbed by the absorbing-body deficit portion 22 and thus, the absorbent article is favorably curved along the roundness in the front-and-rear direction of the buttocks.
