PROBLEM TO BE SOLVED: To provide an inorganic adhesive composition comprising a silica inorganic powder, silicic acid alkali and water and having a viscosity which is less likely to increase even when it is stored for a long time at an ordinary temperature. SOLUTION: The inorganic adhesive composition comprises a silica inorganic powder, an alkali silicate, a non-silica inorganic fine particle having an average primary particle size of≤0.1μm, and water. Preferably, the non-silica inorganic fine particle is an alumina fine particle or titania fine particle. Typically, the inorganic adhesive composition contains≥0.1 pt.mass of non-silica inorganic fine particle based on 100 pts.mass of the silica inorganic fine particle. COPYRIGHT: (C)2010,JPO&INPIT
