[Problem] To provide a sealing material that generates hardly any crystals during use, has excellent fluidity, and enables sealing particularly at 380°C or lower, without relying on V2O5, TeO2, or Sb2O3, etc., and without causing a reaction between a glass powder and a filler powder during baking. [Solution] A low-temperature sealing material containing a lead glass powder and a lead titanate-based filler powder is characterized by: (1) the lead glass containing, as glass components, 1) 69.0-80.0 wt% PbO, 2) 3.1-12.5 wt% Bi2O3, 3) 3.5-11.5 wt% B2O3, 4) 1.7-8.2 wt% ZnO, 5) 0-3.5 wt% SiO2, 6) 0-4.0 wt% CuO, and 7) 1.3-5.0 wt% F; and (2) the weight ratio [PbO/Bi2O3] in the lead glass being 5.6-25.5. |
