PROBLEM TO BE SOLVED: To obtain a sealing material excellent in low-temperature sealing property and maintaining airtightness even when a body to be sealed has a low coefficient of thermal expansion. SOLUTION: The sealing material includes vanadium-based glass powder and refractory filler powder, wherein the vanadium-based glass powder is in an amount of 45-75 vol.%, the refractory filler powder is in an amount of 25-55 vol.%, and the sealing material has a coefficient of thermal expansion of ≤55×10<SP>-7</SP>/°C.
