ABSTRACT:
The invention provides a method for producing a porous body comprising: a starting material mixing step of mixing ceramic particles serving as an aggregate and a sintering aid which includes at least one element selected from the group consisting of rare earth elements, alkaline earth elements, Al and Si such that the amount of the sintering aid is about 1.0% by weight or less relative to the total amount of the ceramic particles and the sintering aid to form a puddle; and a molding and firing step of molding the puddle into a molded body and firing the molded body.
