The present invention relates to a disposable absorbent product such as a disposable diaper, a sanitary napkin, and the like and, more specifically, to: an absorbent product having a nano-coating layer, which is formed on the outer surface of a disposable absorbent product for absorbing excrement to be excreted from the body, thereby enabling overall air permeability of the product to improve and moisture to be blocked； and a manufacturing method therefor. To this end, in the absorbent product making contact with the body so as to absorb and store the excrement and the like to be excreted or discharged from the body, the present invention is characterized in that a nano-coating layer is formed on the outer surface, exposed to the outside, of the absorbent product in order to prevent the absorbed and stored moisture from being discharged to the outside and to ensure air permeability allowing outside air to circulate inside.
