Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an inorganic fine hollow substance which is light in weight, excellent in fire retardant properties and has a desired strength by firing and foaming a raw material of glass substance having a prescribed average particle size and a SiO2 network structure bearing constitution water at a prescribed temperature. SOLUTION: A glass raw material with a SiO2 network structure having an average particle size of 10-50μm and containing >=2wt.% total constitution water is fired and foamed at 850-1,000 deg.C to prepare inorganic fine hollow particles with an average particle size of
