Zusammenfassung:	PROBLEM TO BE SOLVED: To easily perform quality control and to excellently maintain strength even in site work in a porous structural body for buildings or structures and to provide a method for constructing the porous structural body. SOLUTION: The porous structural body has pores which are formed by shrinking or eliminating a water soluble, heat soluble, biodegradable or alkali decomposable pore forming material incorporated into a base material such as concrete constituting the structural body by water dissolution, heat dissolution, biodegradation or alkali decomposition. As the construction method, the base material such as concrete constituting the porous structural body and the water soluble, heat soluble, biodegradable or alkali decomposable pore forming material are kneaded and hardened and at the same time. In this process, the water soluble, heat soluble, biodegradable or alkali decomposable pore forming material is water-dissolved, heat-dissolved, biodegraded or alkali- decomposed to be shrunk or eliminated to form the pores in the structural body.
