Abstract
A resistor, such as a resistor wire, is contained in a sheet, preferably a low density sheet consisting mainly of inorganic fiber. Adsorbent or absorbent (hereinafter "sorbent" collectively) is fixed to the sheet to obtain sorbing characteristics, such that desorption and reactivation can be accomplished by applying an electric current to the resistor to heat the sheet. A sorbing laminate with many channels may be used by laminating the sorbing sheets. The sorbing sheet can therefore be heated directly from the inner side by the resistor contained in the sheet desorbing the sheets rapidly while the time for reactivating the sorbing sheet is reduced and the reactivation efficiency increased.
