Provided is an air-disinfecting device for performing the air disinfection of the inside of a space to be disinfected, efficiently while simplifying the structure of and reducing the size of the device. This device inhibits the feed of electricity to electrodes at the time when electrolyzed water is frozen, thereby to eliminate the load on the electrodes. The device comprises a gas-liquid contact member (8) made of a material having a low reactivity to the electrolyzed water, a water-reserving tank (9) acting as a water reservoir for reserving the electrolyzed water, and a water-absorbing member (19) having its one end portion contacting with the gas-liquid contact member (8) and its other end portion dipped in the electrolyzed water in the water-reserving tank (9).The capillary phenomenon of the water absorbing member (19) is utilized to feed the gas-liquid contact member (8) with the electrolyzed water thereby to bring the air fed to the gas-liquid contact member (8), into contact with the electrolyzed water.
