Participation of water in the formation of multicomponent double electric layer (DEL) on the electrode is experimentally fixed at the presence of the dispersion of alumosilicate. The equivalent circuit of DEL formation in the frame structures saturated with water containing hydroxyl groups and oxides of polyvalent metals in channels of similar structures is offered. At the presence of water the quantity of charge carriers rises resulting from hydrolytic processes; it affects the change of electrophysical properties, namely the extinction of dielectric properties and emersion of conducting ones. The assumption of presence in wet bentonite highly mobile electrons is put forward as the result of the distortion of own structure of the mineral at the presence of water. Water shifts the рН of mineral to the alkaline area, therefore the charge transfer is carried out with the participation of water and OH- of groups of the mineral. In this case the basic transported charge is the electron.
