To improve long-term reliability of a dye-sensitized solar cell by devising a sealing material for the dye-sensitized solar cell having iodine electrolyte solution resistance and suitable for laser sealing.

The sealing material for a dye-sensitized solar cell is a sealing material for the dye-sensitized solar cell containing at least a bismuth-based glass powder and the bismuth-based glass powder contains, by mol%, 25 to 35% (not inclusive of 35.0%) of Bi₂O₃, 20 to 40% of B₂O₃, 11 to 32% of SiO₂, 5 to 20% of CuO, 0 to 20% of ZnO, 0 to 20% of Al₂O₃+ZrO₂ and 0 to 5% of Fe₂O₃ as glass compositions.
