[PROBLEMS] To provide a good weldability to a sensitive part such as a glass sensitive film, a platinum electrode, or a junction made of a porous ceramic, a relatively low temperature softening property, a good workability and workability, and water resistance, weather resistance, and transparency. Provided are an electrode support member for an electrochemical sensor and an electrochemical sensor formed of a glass composition having good properties. An electrode support member of an electrochemical sensor is SiO 2 60 to 75%, Na 2 O 2 to 14%, Li 2 O 0 to 9%, K 2 O 1 to 9% (however, in terms of weight percentage) Na 2 O + Li 2 O + K 2 O 10-25%), SrO 0-9%, CaO 1-9%, BaO 1-6%, MgO 0-6%, ZnO 0-6% (however, SrO + CaO + BaO + MgO + ZnO 10-25%) ) to form a glass composition containing Al 2 O 3 0~6%.
