PROBLEM TO BE SOLVED: To relax a thermal stress being distributed in a radius direction of a metal honeycomb compact by forming a non-joining part of a flat foil and a corrugated foil in the metal honeycomb compact at more than two positions and, by specifying the positions thereof in a given range. SOLUTION: This metal honeycomb compact 2 is formed by laminating a flat foil of a ferritic heat resistant high-alloy steel and a corrugated foil thereof alternately or by enfolding them together. For one round starting from a gas discharge side as a start to a point in the honeycomb compact 2 as an end point, a non-joining part 11 of the flat foil, the corrugated foil contacting part is formed in the compact 2 at more than two positions. At least one of the non-joining parts 11 is made to be located in a scope within 1/2 or less of a radius from the core shaft S of the honeycomb compact 2. In addition, at least one of the non-joining part 11 is made to be positioned apart from the core shaft S at 1/2 or more of the radius, and, at inside of the periphery. Other contacting part of the flat foil and the corrugated foil is made to be a solid diffusion jointed. |
