The present invention provides a moisture control device, a moisture control method, a program, a recording medium, a generated substance, a product, a device, and a device which can improve the characteristics of a substance by controlling moisture. A moisture control device according to an aspect of the present invention is characterized in that a direct current component and/or an alternating current component are applied to at least one electrode that generates at least one of an electric field, a magnetic field, an electromagnetic field, an electromagnetic wave, an acoustic wave, and an ultrasonic wave. The specific voltage or current is such that the moisture existing inside the substance disposed opposite to the electrode is in a combined state, thereby improving the properties of the substance.本發明提供一種可藉由控制水分而提高物質特性之水分控制裝置、水分控制方法、程式、記錄媒體、生成之物質、製品、裝置及設備。本發明之一態樣之水分控制裝置之特徵在於，可藉由對產生電場、磁場、電磁場、電磁波、音波及超音波中之至少一者之至少一個電極施加具有直流成分及/或交流成分之特定之電壓或電流，而使與上述電極對向配置之物質之內部存在之水分彼此為結合狀態，提高上述物質所具有之性質。
