I do. Then, in this state, that is, in a state in which the binder is not dried, the honeycomb body 1 is pressed by the punch 13 or the like and pressed into the outer cylinder 3. At this time, since the outer diameter of the honeycomb body 1 is slightly larger than the inner diameter of the outer cylinder 3, the honeycomb body 1 is press-fitted while being slightly deformed, particularly in the vicinity of the outer periphery, but interposed between the flat plate 1 a and the corrugated plate 1 b. Since the binder has fluidity in an undried state, the honeycomb body 1
Even if it is deformed, it will not fall and will surely maintain the attached state. As a result, the brazing material 2 applied to the binder is maintained without being peeled off and firmly integrated with the binder.

It is transferred into the heater 15 and heat-treated to a temperature equal to or higher than the melting point of the brazing material to braze the flat plate 1a and the corrugated plate 1b and the outer peripheral surface of the honeycomb body 1 and the inner peripheral surface of the outer cylinder 3 firmly. Obtain a metal carrier. In this case, in the present invention, in the heating step, as described above, the honeycomb body 1 is pressed into the outer cylinder 3 in a state where the binder is not dried, and the binder and the brazing material adhered thereon fall. Therefore, the brazing process is performed in a state where sufficient brazing material is present at a predetermined location, and a metal carrier having extremely excellent bonding strength can be obtained.

ましい。FIG. 2 shows a manufacturing process of the second invention. In the first invention, after the brazing material 2 is supplied to the binder surface of the honeycomb body 1, the honeycomb body 1 is dried. Before being pressed into the outer cylinder 3 and then sequentially subjected to the drying process and the heating process.
The second invention is such that the honeycomb body 1 is first pressed into the outer cylinder 3 before the binder is dried, and then the brazing material 2 is supplied to the binder surface of the honeycomb body 1, and then the drying process and the heating process are sequentially performed. It is to be. The respective steps in this case are the same as the respective steps in the first invention. In this case, compared to the first invention, since the honeycomb body 1 is press-fitted before the brazing material supply step and there is no deformation force applied to the brazing material,
Further improvement in bonding strength can be achieved. Also in this second invention, before the honeycomb body is press-fitted into the outer cylinder, the outer peripheral surface of the honeycomb body 1 is provided with a bonding foil braze 4 for bonding to the outer cylinder 3 or is bonded to the outer cylinder. It is preferable to apply a brazing material.
