Abrégé
(EN)
Provided is a method for manufacturing a porous body characterized in that after dispersing a gas generating compound in a molten-state material for forming the porous body, the molten material is solidified. The high quality and highly uniform porous body can be manufactured even at an atmospheric pressure, without requiring high pressure ambience. ©KIPO&WIPO 2009
