(57) Abstract: A honeycomb forming die capable of forming a thin-walled ceramic honeycomb structure having a cell wall of 45 to 120 µm, and a method for manufacturing the same. A groove 2 is formed on a surface of a cell block 3. And a honeycomb having a structure in which a clay introduction hole 4 communicating with the slit 3 is provided on the back surface, and a corner 3a of a surface of each cell block 4 forming the slit 2 is formed of a rounded R portion. In the molding die 1, each cell block 3 is formed of a cell block body 11, a first coating film 12 formed by performing electroless plating on the cell block body 11, and a chemical vapor deposition on the first coating film 12. And a second coating film 13 formed by performing Get. |
