PROBLEM TO BE SOLVED: To provide an absorbent core which is used for disposable absorbent article containing porous absorbent gelling materials for absorbing menses or blood and improves influences on a fluid catching capability due to partial cover of an outer surface of an absorbent polymer material with the layer of a thermoplastic material.SOLUTION: An absorbent core includes a base material layer 100 including a first surface and a second surface. The absorbent core further includes a layer of an absorbent polymer material 110 including a first surface and a second surface. The absorbent core also includes an adhesive layer 120 including a first surface and a second surface. The layer of an absorbent polymer material is included between the adhesive layer and the base material layer. The second surface of the absorbent polymer material layer is in contact with the first surface of the base material layer, and the first surface of the absorbent polymer material layer is in contact with the second surface of the adhesive layer. The layer of the absorbent polymer material further contains porous absorbent polymer particles having bulk density ranging from 0.01g/cmto 0.4g/cm.
