An electrode-coating glass composition of the present invention satisfies -9.5<=A<=-4, 3000<=B<=3900 and 240<=C<=320 in Fulcher's equation logeta=A+B/(T-C), which defines the temperature (T[° C.]) dependence of viscosity (eta[dPa.s]). Furthermore, the absolute value |Deltalogeta| of the difference between values of logeta at temperatures of 50° C. above and below a softening point is at least 4.2. Such an electrode-coating glass composition can be achieved, for example, by a glass composition containing at least one of BaO and Al<SUB>2</SUB>O<SUB>3</SUB>, and 40 to 66 wt % of PbO, 2 to 25 wt % of SiO<SUB>2</SUB>, 5 to 40 wt % of B<SUB>2</SUB>O<SUB>3</SUB>, 0 to 20 wt % of BaO, 0 to 8 wt % of Al<SUB>2</SUB>O<SUB>3</SUB>, 0 to 2 wt % of CuO, and 0 to 2 wt % of CeO<SUB>2</SUB>. |
