First, in order to apply the brazing material to the peripheral portion 81 of the honeycomb body 8, masking is applied to one end surface of the honeycomb body 8 so as to cover the non-brazing material application portion (the central portion of the one end surface of the honeycomb body excluding the peripheral portion). The brazing material is placed in the peripheral portion 81 of the honeycomb body 8 and the excess brazing material is sucked and removed from the other end surface side. Next, in order to apply the brazing material to one end portion 82 of the honeycomb body 8, the honeycomb body 8 is placed in a dipping tank in which the brazing material is put.
The one end portion 82 is dipped to apply the brazing material, and the excess brazing material is sucked and removed from the one end surface side. And the honeycomb body 8
In order to apply the brazing material to the other end portion 83 of the honeycomb body 8, the other end portion 83 of the honeycomb body 8 is dipped in the dipping tank to apply the brazing material, and the excess brazing material is sucked and removed from the other end surface side. . After that, the brazing material application portion is joined by heating.
