A humidity control apparatus for realizing the dehumidification, humidification, and ventilation operations in a compact configuration. The apparatus includes a rotary humidity control element, an electric heater, and sucking and/or forcing blowers. The rotary humidity control element is of metal silicate gel polymerized in honeycomb laminates of ceramics, and is sectioned into a drying function part, a heat recovery function part, and a humidification function part, for use. The drying function part absorbs and removes moisture from air passing therethrough at room temperatures. The heat recovery function part recovers heat of air passing therethrough. The humidification function part moistens the air passing therethrough if the air is high in temperature. The electric heater is provided on an air passageway between the heat recovery function part and the humidification function part, for heating the air to be introduced to the humidification function part. The first suction- or forcing blower is provided on a first air passageway, and the second suction- or forcing blower is provided on a second air passageway. By the action of the blowers, an outdoor and interior airs are fetched from the exterior and the interior respectively, passed through the rotary humidity control element, and discharged. The air passageways are changed so that the apparatus is operated for dehumidification, humidification, or ventilation selectively.
