A porous mold for pressure slip casting, which includes: a surface porous layer having an average pore diameter of at most 20 microns and a thickness of 5 to 40 mm; an adhesive applied in a pattern to the rear surface of the surface porous layer to leave an unapplied portion on the rear surface; a coarse porous layer covering the adhesive applied and unapplied portions of the rear surface of the surface porous layer and made of a mixture of a liquid resin and a filler of a particle diameter of 0.1 to 5.0 mm at a volume ratio of 15 to 50:100, the coarse porous layer having a thickness of 5 to 30 mm; a sealing adhesive covering substantially the outer surface of the coarse porous layer; and a passage for water from and air into the coarse porous layer.
