HUMIDIFIER AND VENTILATOR

PROBLEM TO BE SOLVED: To obtain a humidifier with a small wind resistance (pressure loss) capable of increasing an amount of water absorption of a water-absorbing member without complicated structures for reducing costs of manufacture.SOLUTION: A humidifier 1 comprises: a humidification element 2 composed of a plurality of disks 3 which are laminated with a gap between respective disks; a motor 5 for rotating the humidification element 2; and a water-storage container 6 in which a part of the humidification element 2 intrudes. Ribs 4 are formed at outer peripheral parts of both lateral faces of the disk 3, the ribs reaching outer peripheral edges. When the humidification element 2 is rotated by the motor 5, part of water stored in the water-storage container 6 is pumped up by parts of the ribs 4, which are immersed in stored water 8, among the ribs 4, while part of the pumped stored water 8 starts to flow toward lateral faces of the disk 3 by the separation of the ribs 4, which have pumped up part of the stored water 8, from the stored water 8.
