<P>PROBLEM TO BE SOLVED: To provide an electrode body capable of preventing that an outflow of components of an internal liquid which passes through a liquid junction changes to suddenly become electrically unstable by temperature variation and adhesion of a bubble and a smudge to the liquid junction. <P>SOLUTION: A liquid junction 11 is constituted by providing: a first liquid junction part 11a formed of a porous resin, which is arranged so as to surround an internal liquid storage part 15; and a second liquid junction part 11b formed of a columnar porous ceramic, which extends in the thickness direction of a wall part 12 dividing between the internal liquid and a liquid for test to form the internal liquid storage part 15 and is embedded in the wall part 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
