Abstract
An electric thermo pot provided with a coating layer formed on the inner surface of the vessel containing powdered charcoal. Electric thermo pot of the present invention improves quality of liquid kept therein. It is generally believed that the liquid quality is improved presumably by infrared ray radiated from the powdered charcoal contained in the layer. Presumable causes for the improvement also include a very small amount of certain elements dissolving out of the powdered charcoal into the liquid and an effect of absorption pertinent to the powdered charcoal.
