Abstract
A die was provided 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 die is made of cemented carbide having wear resistance. The cemented carbide is formed by compacting, followed by sintering at high temperature, metal carbide powder of transition metal element series with an iron group metal binder having toughness. A connection area ratio of the back hole and the cell block is 35 to 65%.
