Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an absorber having an excellent fitting property, wearability, and absorbing property.

SOLUTION: An absorber 14 comprises an absorption core 47 containing a super absorbent polymer and an intermediate layer 43 in the thickness direction T. The absorber 14 is segmented in a crotch region MA and in the width direction into an absorption core overlapping region C2OP overlapping with the absorption core 47 in the thickness direction T and a pair of absorption core non-overlapping regions C2NP not overlapping with the absorption core 47 in the thickness direction T and disposed at both ends of the absorption core overlapping region C2OP. The intermediate layer 43 comprises an intermediate layer overlapping part 43OP and a pair of intermediate layer non-overlapping parts 43NP that are disposed in the absorption core overlapping region C2OP and the pair of absorption core non-overlapping regions C2NP, respectively, in the crotch region MA. In the crotch region MA, an average basis weight or a thickness of each of the pair of intermediate layer non-overlapping parts 43NP is smaller than an average basis weight or a thickness of the intermediate layer overlapping part 43OP.
