ABSTRACT:
An absorbent product capable of preventing the absorbing rate from significantly lowering with the elapse of time, from the start of use to a final stage when the absorbing capacity of the product reaches a limit, is provided. The absorbent product has a very small re-wet amount. The absorbent product includes a liquid-impermeable surface sheet positioned on the upper side, a liquid-impermeable back sheet positioned on the lower side, and an absorber containing super absorbent polymer to absorb discharged liquid positioned between the surface sheet and the back sheet, wherein a flow passage is provided to allow a part or all of the discharged liquid supplied to the surface sheet to move to a side of the back sheet.
