PURPOSE:To strengthen fusing strength between bodies and to prevent stripe-like patterns and cracks from occurrence, by bending communicating paths of ceramic body feeding holes communicated to molding channels whose barrier thickness is large. CONSTITUTION:A mold 1 is constituted of ceramic body feeding holes 3, 3a-3e mainly placed at the extrusion molding machine side and molding channels 2, 2a-2e communicating the feeding holes and molding the ceramic body fed in the feeding holes to a required ceramic honeycomb structural body, and the mold 1 has bent communicating paths of ceramic body feeding holes 3a and 3e communicated to molding channels 2a and 2e whose barrier thickness is large. As shearing force is thereby applied on the ceramic body fed from the feeding holes, and the ceramic body is pushed out in the lateral direction, fusing force of ceramic bodies mutually becomes stronger and no defect occurs in the ceramic honeycomb structural body thus obtained.
