PROBLEM TO BE SOLVED: To bond a honeycomb to an outside cylinder at a right position and to set up bond strength optionally by applying brazing material paste on the outer surface of the honeycomb through a through hole with a mask arranged and brazing the outside cylinder to the outer surface. SOLUTION: First, a mask 1 having a through hole 10 is arranged on the outer surface of a honeycomb, and brazing material 3 paste is applied on the outer surface of the honeycomb. For example, a mask 1 film is wound onto the surface of the honeycomb, the brazing material 3 is supplied and applied by a screen printing method. In this way, the brazing material 3 can be applied in spots on the surface of the honeycomb. Next, the honeycomb coated with the brazing material 3 is inserted into an outside cylinder and heat-treated so that the honeycomb can be bonded to the outside cylinder in spots. Accordingly, the manday can be reduced, and the positional accuracy of the brazing material 3 on the honeycomb body can be improved surely. |
