To provide a thin absorbent with a high absorption speed, and an absorbent article.

An absorbent body 1 has a lower absorption layer 2 including a hydrophilic porous body 21 and an absorbent polymer 22, and an upper absorption layer 3 laminated on the lower absorption layer 2 and including non-woven fabric 31 and an absorbent polymer 32. The hydrophilic porous body 21 comprises cellulose-based sponge preferably. Also, the lower absorption layer 2 is practically vertically long, it is preferable that the distribution amount of the absorbent polymer 22 at the width direction center part of the lower absorption layer 2 is smaller than the other part of the lower absorption layer 2, and especially it is preferable that the absorbent polymer 22 is not practically present at the width direction center part of the lower absorption layer 2. Also, the non-woven fabric 31 comprises air-through non-woven fabric preferably.
