Beschreibung
Zusammenfassung:	A honeycomb segment-forming die includes: an introducing portion 3 provided on an introduction face 8 side and having a plurality of back holes 7, and a forming portion 2 provided on an formation face 4 side and having slits 6 communicating with the back holes 7. The forming portion 2 has a polygonal outer peripheral shape and forms a prismatic honeycomb segment by passing kneaded clay for forming which is introduced from the back holes 7 of the introducing portion 3 through the slits 6 of the forming portion 2, and a gap L1 between slits 6 formed in each of corner portions 11 including a vertex of the polygonal forming portion is larger than a gap L2 of slits 6 formed in the central portion 12 of the forming portion 2. This enables to form a honeycomb segment having high compressive strength.
