Abstract
The present invention is characterized by a solid body disposed so that a remarkably small gap may be formed between it and a surface of an electrode. A super-thin liquid membrane is formed in the small gap by an interfacial tension of a liquid. An object to be measured is applied to or acted upon either the solid body or the super-thin liquid membrane. An electric signal due to the physical properties of the super-thin liquid membrane itself or an electric signal due to a chemical or physical reaction, which is generated on an interface of the solid body and the super-thin liquid membrane and diffused through the super-thin liquid membrane itself, is detected by means of the electrode to measure the physical properties of the object to be measured.
