An electronic wetness-sensing absorbent article, comprising: a flexible waterproof thin film comprising a polyethylene thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and used to absorb a liquid entering from the water-permeable braided fabric layer, the liquid comprises urine, wherein the flexible electrodes and the absorbent layer are located on the two surfaces of the flexible waterproof thin film respectively and are mutually separated and insulated from each other; and the flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor, in which the flexible electrodes serve as electrodes of the electrolytic capacitor, the flexible waterproof thin film serves as a dielectric of the electrolytic capacitor, the liquid comprising urine serves as an electrolyte of the electrolytic capacitor, and the wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof, wherein the absorbent layer comprises a first absorbent and a second absorbent mixed in the first absorbent, the first absorbent comprises water storage spaces formed by wood pulp and is used to absorb the liquid entering from the water-permeable braided fabric layer and thus increase the capacitance value of the variable electrolytic capacitor, and the second absorbent comprises a granular macromolecular water-absorbing resin and is used to absorb the liquid from the first absorbent and thus reduce the liquid content in the first absorbent and the wet area of the first absorbent, so as to reduce the capacitance value of the variable electrolytic capacitor, the water-permeable braided fabric layer comprises a nonwoven fabric, the absorption rate of the first absorbent is faster than that of the second absorbent, the liquid absorption capacity of the second absorbent is higher than that of the first absorbent, and the second absorbent has water absorption and retaining capacities, such that a process that the liquid migrates from the first absorbent to the second absorbent is realized; the process is dynamically reflected by the change of the capacitance value. a flexible waterproof thin film comprising a polyethylene thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film;
