Abstract: An electronic diaper and its manufacturing method includes a diaper body and sensing wires positioned on the diaper body, and an electronic device to connect with the sensing wires so as to get signal from the sensing wires about the condition of the diaper body. If the sensing wires are connected electrically by urine absorbed by the diaper body, then the electronic device gets signal from the sensing wires to operate to light up an LED or let a speaker sound out so as to give out an alarm that the diaper body has wetted to be replaced with a new one. The electronic device is separatively combined with the diaper body so as to be used repeatedly in spite of the diaper body having to be discarded when wetted by urine.
