<P>PROBLEM TO BE SOLVED: To provide an electrode support member of an electrochemical sensor, formed of a glass composition which is improved in weldability with a sensing part, such as a glass-sensing film, a platinum electrode or the like or a junction made of porous ceramics, having relatively low-temperature softening properties and proper processability, fine processability, resistance to water, weatherability and transparency, and provide also an electrochemical sensor. <P>SOLUTION: The electrode support member of the electrochemical sensor is formed of a glass composition, containing 60-75% SiO<SB>2</SB>, 2-14% Na<SB>2</SB>O, 0-9% Li<SB>2</SB>O, 1-9% K<SB>2</SB>O (where Na<SB>2</SB>O+Li<SB>2</SB>O+K<SB>2</SB>O: 10-25%), 0-9% SrO, 1-9% CaO, 1-6% BaO, 0-6% MgO, 0-6% ZnO (where SrO+CaO+BaO+MgO+ZnO:10-25%) and 0-6% Al<SB>2</SB>O<SB>3</SB>on weight percent basis. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
