FIG. 7 is a graph showing the relationship between the width B of the space and the number of pores generated per 200 mm of welding length, obtained by experiments. That is, from this figure, the number of generated pores significantly decreases as the width B of the space portion increases, and when the width B of the space portion is 7 mm or more, the end of the brazing material 5 faces the abutting portion during welding. However, it has been clarified that the occurrence of welding defects due to the inflow or infiltration of the brazing material 5 into the welded portion is reduced to a negligible level. Therefore, in this embodiment, the width of the space 11 is set to 7 mm.
