摘要： There is provided a mold for extrusion forming of ceramic articles which is excellent in wear resistance and can remarkably decrease forming defects in the vicinity of outer peripheries thereof. The mold for the extrusion forming of the ceramic articles includes a die 1 having a plurality of back holes 9, and slits 8; a back pressing plate 12 and a back spacer 13 to adjust the amount of the kneaded clay to be supplied; and a pressing plate 11 and a spacer 10 to regulate the shape and size of the formed ceramic article. At least a portion of the supply end 22 of the die 1 which overlaps with the back pressing plate 12 is flattened, and a surface roughness (Ra) thereof is in a range of 0.05 μm to 10 μm.
