Description of the Related Art Conventionally, when a metal carrier is manufactured, a corrugated sheet and a flat plate are wound up, and the corrugated plate and the flat plate are partially joined. There has been performed a brazing method in which a honeycomb body having a flat plate wound thereon is immersed in a binder, and then a brazing material is adhered to a binder-attached portion, and heat treatment is applied to join the corrugated plate and the flat plate. When the binder is immersed in this brazing method, a suction phenomenon due to surface tension occurs in the honeycomb body, and as a result, it is difficult to accurately control the joining length, and the boundary between the binder-attached portion and the unattached portion is unclear.

ことを目的とする。When a corrugated plate and a flat plate in a conventional honeycomb body are partially joined, as described above, the binder adheres more than necessary due to surface tension,
The bonding area is increased by adhering to the portion where the binder is not adhered. In addition, there is a problem that the quality of the carrier varies greatly because the attachment portion cannot be controlled to be constant. The present invention is to solve such a conventional problem, and provides a stable quality metal carrier by clearly supplying a binder to a predetermined portion of a honeycomb body and bonding only a desired portion. It is intended to provide a joining method.

That is, the binder adhesion preventing agent 2 is partially adhered to the flat plate 1, and then the flat plate 1 and the corrugated plate 3 shown in FIG. 2B are overlapped and rolled up to form the honeycomb body 4 shown in FIG. 4 is immersed in a binder solution, for example, as shown in FIG. Reference numeral 5 denotes a binder non-adhered portion, and reference numeral 6 denotes a binder adhering portion. The boundary between the portions is clear, so that the problem of absorption due to the surface tension of the binder liquid, which has conventionally been a problem, is eliminated, and the variation in the binder adhering portion can be eliminated. . Subsequently, when a brazing agent is adhered to the binder attaching portion 6 and heat treatment is performed to join the flat plate 1 and the corrugated plate 3, the joining length can be accurately controlled, which is extremely advantageous. In the figure, reference numeral 7 denotes an outer cylinder housing the honeycomb body 4 and 8 denotes an outer cylinder 7
