Abstract
Disclosed is a die () for forming a honeycomb body having a structure provided with groovy slits () on a front face thereof, the slits being formed by cell blocks () and back holes () on a back surface thereof, each hole being communicatively connected with the slit. The number N of the cell blocks per one side of the die is even number. According to the die for forming the honeycomb body, strain generated on an extruded face of the honeycomb body after extrusion and bending of the honeycomb body can be reduced as well as the die can maintain a stable frictional force of extrusion and is excellent in extrudability and wear resistance.
