A mold having a shell and a porous layer formed on the surface of the cavity of the shell. The mold can be suitably used for manufacturing a porous body having a porous layer on the surface thereof. The method for manufacturing the mold, includes the steps of forming a layer of combustible powdery particles around a wax mold, which is a lost pattern, a step of forming a film of a ceramic precursor slurry around the wax mold having powdery particles formed thereon, a step of subjecting the resultant product to a heat treatment, to thereby dewax the wax mold, and a step of firing the slurry film, to thereby burn and vanish the powdery particles in the slurry film and form a shell.
