A humidification device has an evaporation filter, a water supply device, and a fan device. The evaporation filter uses as a filter base material a three-dimensional structure formed by interconnecting, by connection fibers, a first base material having openings and a second base material having openings, and the first and second base materials are interconnected such that the openings of both the base materials communicate with each other. The water supply device supplies water to the evaporation filter to wet the filter base material. The fan device sends air to the wet filter base material, allows the air to pass through the communicated openings, and sends humidified air out of the evaporation filter. A decrease in humidification ability of the humidification device is suppressed even if scale is deposited on the evaporation filter. Further, contact efficiency between passing air and water present on the evaporation filter is enhanced, and as a result, although compact in size, the humidification device has high humidification performance. |
