The inventive sealing material comprises a mixture of Materials A and B, the Material A containing fine-particle silica produced by a process in which a slurry having metallic silicon powders dispersed in water is jetted into a flame for burning and oxidization and having an average particle diameter of 1.0 µm or less, a dispersant and water and being subjected to wet dispersion, and the Material B containing a calcium compound having an average particle diameter of 1.0 µm or less, a dispersant and water and being subjected to wet dispersion. The average particle diameter is measured using a leaser diffraction type particle size distribution analyzer without subjecting the silica and the calcium compound to ultrasonic dispersion. The fine-particle silica is fine-particle spherical silica having an average sphericity of 95% or more, and the calcium compound is calcium hydroxide. Preferably, the sealing material should further contain a hardening time regulator. Preferably, the Material A and/Material B should be produced by a pulverizer using high-pressure water.
