SPINNERET FOR MOLDING HONEYCOMB STRUCTURE AND MANUFACTURING METHOD THEREFOR

Disclosed is a die for forming a honeycomb structure 1, including: a second plate-shaped portion 3 that is formed of iron or the like and has a second bonded surface 6, where a back hole 5 for introducing a forming raw material is formed; and a first plate-shaped portion 7 that has a first bonded surface 10 and is formed of tungsten carbide based cemented carbide, where a slit 9 communicating with the back hole 5 to form a forming raw material is formed, and a cavity 11 communicating with the back hole 5 and the slit 9 is formed in the first bonded surface 10 side, wherein the first plate-shaped portion 7 is arranged on the second plate-shaped portion 3 such that the first bonded surface 10 comes into contact with the second bonded surface 6, an open end of the cavity 11 on the first bonded surface 10 has a diameter different from that of an open end of the back hole 5 on the second bonded surface 6, and the open end 11a of the cavity 11 on the first bonded surface 10 is arranged inside the open end 5a of the back hole 5 on the second bonded surface 6. It is possible to suppress a distortion in the honeycomb structure.
