PURPOSE: To provide a porous body excellent in strength and heat insulating property and capable of producing at normal temp. and pressure.
CONSTITUTION: This porous body is a foamed hardened body constituted of a combined component of phosphoric acids, a multivalent metallic oxide, a resin emulsion, water and a foaming agent or a frother and furthermore one or more kind of components selected from (among) a multivalent metallic compound, a hydraulic cement, an aggregate, an inorganic thickener and an inorganic or organic fiber with these components and the ratio of (alkaline earth metal atom total number)/(phosphorous atom total number) is regulated to 1.2-2.1 and (aluminum atom total number)/(phosphorous atom total number) is regulated to ≤0.7.
