Abstract
A method of preparing an inorganic porous member causes a layered inorganic compound in swelled state with a solvent contained therein to be dried in a super critical state, so as to have holes held between respective layers of the inorganic compound, whereby the layered compound can be excellently maintained with less agglomeration caused upon removal of the solvent and the hole volume in the entire inorganic porous member can be remarkably increased.
