PROBLEM TO BE SOLVED: To provide a humidity conditioner enabled, by making a humidity fluctuation gentle, to stabilize the humidity in the conditioner and to reduce a power consumption.SOLUTION: A humidity conditioner 1 comprises: a dehumidification unit 2A for dehumidifying its inside 10, when the humidity of the inside 10 is at or higher than a first threshold value; a humidification unit 2B for humidifying the inside 10 when the humidity of the inside 10 is at or lower than a second threshold value lower than the first threshold value; and a humidity control sheet 5 adhered to the inside 10. The humidity control sheet 5 is made of a woven fabric or a nonwoven fabric containing acrylate polymer fibers, for example, and is characterized by high hygroscopicity in a high moisture and by absorbing humidity in the case where the ambient moisture transits in a rising direction, and releasing humidity in the case where the ambient moisture transits in a lowering direction. Thus, an abrupt moisture fluctuation of the inside 10 is suppressed so that the moisture change of the inside 10 can be made gentle and stabilized within a predetermined range (from the second threshold value to the first threshold value). 【課題】湿度変動を穏やかにして庫内の湿度を安定させることができ、かつ消費電力を低減させることのできる調湿庫を提供する。【解決手段】調湿庫１は、庫内１０の湿度が第一のしきい値以上である場合に庫内１０を除湿する除湿ユニット２Ａと、庫内１０の湿度が第一のしきい値より低い第二のしきい値以下である場合に庫内１０を加湿する加湿ユニット２Ｂと、庫内１０に貼り付けられた調湿シート５と、を備えている。調湿シート５は、例えばアクリレート系ポリマー繊維を含む織布あるいは不織布であり、高湿度の吸湿性が高く、かつ周囲湿度が高くなる方向に遷移する場合に吸湿し、低くなる方向に遷移する場合に放湿する特徴を有する。このため、庫内１０の急激な湿度変動が抑制され、庫内１０の湿度変化を緩やかにして、所定範囲（第二のしきい値〜第一のしきい値）内に安定させることができる。【選択図】図１
