- and
- a super absorbent polymer layer between the first nonwoven fabric and the second nonwoven fabric,
- wherein the super absorbent polymer layer comprises a super absorbent polymer and an adhesive,
- wherein the super absorbent polymer layer is adhered to the first and second nonwoven fabrics by an adhesive, and the super absorbent polymer layer does not contain pulp, and
- the following conditions (1) and (2) are satisfied:
- (1) a retention rate obtained by measuring an amount of super absorbent polymer remaining in the absorbent body without leakage after vibrating the absorbent body 100 times at a frequency of 65 times/min and an amplitude of 15 mm is 90% or more, and
