This disclosure relates to a formed body having activated carbon granules bondedly carried by an inorganic substance body consisting of a sintered body or fused body of inorganic substance powder. The formed body preferably is of a honeycombed structure. The formed body is not only high in strength, excellent in absorbing ability, long in service life, but also permits of molding into various shapes fit for uses. The invention also relates to a method of producing the formed body of the type described above. The method essentially follows the conventional ceramic firing art or ceramic production art.
