Abstract

PURPOSE:To prolong the life of electrode, by fixing the surface of ion-sensitive membrane so as to be flush with the edge face of the main body of a cylindrical tube. CONSTITUTION:A sensitive membrane 1 dispersed an ion selective and sensitive substance in a high-molecular resin, is melt-stuck with a cylindrical main body 3 composisting of the high-molecular resin so as to be flush with the edge face of the body 3 and a reference liquid and an electrode are provided in the body 3. Thus constructed electrode has the following features; the area of the membrane 1 in contact with a sample of living body is small and the sensitive substance or plasticizer is difficult to combine with or to elute various kinds of ions in the sample of living body and also the stability of measurement is improved and moreover, the life is prolonged.
