A refrigerator, as a mist producing mechanism, uses a static atomizing device, can not generate the harmful gas such as ozone and the like, and produce the mist with the degerming effect to supply for a store room. The static atomizing device (36) is arranged on a division board (8) between a refrigerating chamber (3) and a vegetable chamber (4). The water (W) in a water storage tank (430 is supplied to a mist discharging part (49) through a water sucking pin (48), a water-retentive material (47) and a conductive thin plate (46). The high voltage is exerted on the mist discharging part (49) from a direct current high voltage supply apparatus (56), and the mist containing a hydroxyl with stronger oxidation effect is discharged by the discharge of the mist discharging part (49). The mist is supplied into the vegetable chamber (4) from a mist outlet (52).
