。[Claims for Utility Model Registration] (1) An outer cylinder housing having at least one opening, a membrane holder attached to the opening of the outer cylinder housing, and a membrane holder fixed to the membrane mounting surface of the membrane holder. and a flexible gas permeable membrane that is in contact with the part where the measurement gas is present, and a flexible gas permeable membrane that is exposed from a support supported by the outer housing and that is arranged independently of each other within the outer housing. a liquid storage chamber that is formed between the electrode, the reference electrode, and the counter electrode, and the outer cylindrical housing and the support body and that accommodates an internal liquid so as to be in contact with the electrode and the gas permeable membrane; and a liquid storage chamber that is filled with the liquid storage chamber. A protrusion comprising a predetermined internal liquid and screw means that allows relative movement between the outer cylinder housing and the support in the axial direction, and a working electrode is exposed on the side of the support opposite to the gas permeable membrane. and a tapered end surface portion exposing a reference electrode and a counter electrode, and the outer case is relatively moved in the axial direction by the screw means so that the gas is applied only to the working electrode located on the protrusion of the exposed end surface. An electrode body for gas concentration measurement characterized by having a permeable membrane elastically pressed into contact. (2) The electrode body for gas concentration measurement according to claim 1, wherein the tapered end face is constituted by a curved surface such as a conical surface or a paraboloid. (3) The electrode assembly for gas concentration measurement according to claim 1, wherein the membrane mounting surface of the membrane holder has a concave membrane supporting surface portion. (4) The electrode assembly for gas concentration measurement according to claim 1, wherein the gas permeable membrane is fused to the membrane mounting surface of the membrane holder. (5) The electrode assembly for gas concentration measurement according to claim 1, wherein the gas permeable membrane is fixed to the membrane mounting surface of the membrane holder by an O-ring.
