る。Problems to be Solved by the Invention Honeycombs formed using such a die device have a lattice formed on the entire surface, and in order to obtain a hollow honeycomb, once the honeycomb is formed, it must be further drilled. Therefore, it is necessary to drill holes, which takes a lot of man-hours, it is difficult to obtain holes of a predetermined size, and lattice defects and cracks occur during processing, which makes processing difficult in practice.
