摘要： A flat tube having a nearly B-like shape or the like in cross section, which has one or more partitions therein, and is coated with a brazing metal on the outer surface thereof, is provided. In the top portion of the turned-up portion constituting the partition, there are formed many slits, in order to provide the conditions that satisfy both of the brazing performance and an increase of working accuracy of the flat tube, which slits allow the brazing metal to enter up to the top portion of the turned-up portion, wherein the length “c” of the slit is 2 mm to 15 mm; the distance “e” between the edges of the neighboring slits is 3 mm to 10 mm; and “e/c” is 0.6 or more.
