Abstract: A raw setter has a plate shape, is made of the same material as in a honeycomb formed body, and has a chamfered portion in which a circumferential portion of one end face is chamfered in an oblique direction and whose has a tapered cross-sectional shape by reducing a diameter of an end face portion to an outer diameter, a ratio of an area of a flat portion to an end face area is from 10 to 85%, an angle formed between the flat portion and the chambered portion is from 3 to 50°, a flatness of each of the flat portion of the one end face and a flat portion of the other end face is 0.3 mm or less, and a thickness of cell partition walls is 0.1 mm or less.

Abstract: A die has two surfaces, in a forming material supplying surface which is one surface, a plurality of back holes to introduce a forming material of a honeycomb formed body into the die are formed, and in a honeycomb formed body extruding surface which is the other surface, lattice-shaped slits corresponding to cell partition walls are formed, the back holes communicate with the slits in slit intersecting portions of the slits, polygonal cell blocks defined by the slits include chamfered portions in which parts of corner portions and the like are chamfered at a chamfering angle θ of 1.0 to 8.0° to the extruding direction, from the honeycomb formed body extruding surface toward a slit depth direction, and straight portions which are not chamfered, and a ratio of a length L of the straight portion to a slit depth D is from 20 to 60%.
