PROBLEM TO BE SOLVED: To obtain a metallic carrier excellent in durability over a long period by forming a desired wide end face edge part along the outer peripheral part of end face part of exhaust gas flow-in side of a metallic honeycomb body into a structure reduced in the opening ratio of a cell existing on the end face edge part by the bent chip of a flat belt like material existing on the end face edge part. SOLUTION: In the metallic honeycomb body H used for the metallic carrier MS, the structure of the end face part H1 of the exhaust gas flow-in side is constituted so that the end face part H1 is divided into a flat part Ha, where the main region including the central part of the end face part H1 has flat surface, and an end face edge part Hb, which is along the outer peripheral part of the flat part Ha, and in the end face edge part Hb, the opening ratio of the cell (opening path of exhaust gas flow passage) 3 existing at a part of the end face edge part Hb is reduced by the bent chip 11 of the flat belt like material of the structural member of the metallic honeycomb body H. The bent chip 11 is formed by bending after the S-shaped metallic honeycomb body H is formed by winding a stack S. |
