PROBLEM TO BE SOLVED: To produce a foamed glass capable of satisfactorily being foamed even at a low heating temp. SOLUTION: When glass materials are foamed to obtain a foamed glass, a coarse particulate glass having 400-1,000μm particle size and a fine particulate glass having <=200μm particle size are used as the glass materials, the proportion of the coarse particulate glass is adjusted to 10-50 wt.%, silicon carbide is used as a foaming agent and <=800 deg.C heating temp. is adopted.
