A method of fabricating at least a honeycomb body and a drying system are disclosed, in which a plurality of honeycomb bodies each having a multiplicity of cells arranged in the shape of a honeycomb and having a wall thickness of 0.125 mm or less can be dried without developing any cracking, wrinkling, etc. in the outer peripheral skin portion of the mold. A plurality of extrusion-molded argillaceous honeycomb bodies are dried in such a manner that each honeycomb body is placed on a corresponding conveyance tray of porous ceramics having a dielectric loss of 0.1 or less, a porosity of 10% or more and a sectional open area ratio of 50% or more is exposed to a high-humidity ambience of 70% or higher in humidity while at the same time being irradiated with. microwaves of 1,000 to 10,000 MHz. As an alternative, a plurality of extrusion-molded argillaceous honeycomb bodies are dried by being exposed to a high-humidity ambience of 70% or more while at the same time being irradiated with microwaves of 1,000 to 10,000 MHz, after which hot air is applied to the honeycomb bodies in such a manner as to pass through the cells thereof.
