A metal carrier has advantages such as excellent temperature rising characteristics and impact resistance as compared with a ceramic carrier, and thus has been used in recent years as a carrier for an exhaust gas purifying catalyst for vehicles, for example. The metal carrier usually has a structure in which a honeycomb portion is housed in an outer cylinder, and the honeycomb portion is manufactured by alternately stacking a flat plate made of a thin metal plate and a corrugated plate, for example.

Therefore, joining of the honeycomb portion and the outer cylinder becomes a problem. A metal carrier in which the honeycomb portion and the outer cylinder are wholly joined together in the circumferential direction and the axial direction of the contact portion is disclosed in, for example, JP-A-56-4373, JP-B-47-48109, and JP-B-55-32424.

However, the expansion coefficient of the metal carrier is larger than that of the ceramic carrier. Therefore, when a temperature difference is generated between the central part and the outer peripheral part of the exhaust gas purifying catalyst using the same, the exhaust gas flow velocity is high and the honeycomb part and the outer cylinder are separated. In some cases, stress is generated in the joint part of the honeycomb structure and the honeycomb part is broken. Also, due to the difference in material between the honeycomb part and the outer cylinder, there is a difference in expansion coefficient,
After all, the honeycomb part may be broken. In particular, when a metal carrier is used as a catalyst for purifying exhaust gas of an automobile, the honeycomb portion is likely to be broken in the cold heat durability test.

As described above, in the metal carrier of the present invention, 30-80% of the contact portion between the honeycomb portion and the outer cylinder in at least one cross section in the direction orthogonal to the axial direction is brazed, so that stress due to heat or vibration is applied. Since the peeling between the honeycomb portion and the outer cylinder is suppressed, durability and reliability are improved. Further, since it is possible to make a large difference in the coefficient of thermal expansion between the material used for the honeycomb portion and the material used for the outer cylinder,
The degree of freedom in selecting materials has increased. Further, since the amount of brazing material used can be reduced as compared with the entire brazing of the honeycomb portion and the outer cylinder, the manufacturing cost is also reduced.
