Abstract

A flat tube (10) of a heat exchanger has a curve section (13). At least a part of the curve section (13) is constructed by overlaying an outer edge section (22) on the outer side of an inner edge section (21). The inner edge section (21) has a small curve region (102). The small curve region (102) tilts relative to a flat plate section (11) and is defined by a radius greater than the difference between half the thickness (d1) of the flat tube (10) and the plate thickness of the outer edge section (22). The small curve section (102) is provided at a position not beyond the center line (C1) in the thickness direction of the flat tube (10). The outer edge section (22) extends beyond the center line (C1). An end surface (22a) of the outer edge section (22) is located in the small curve region (102). The flat tube (10) has, near a hole (54), expanded opening sections (15, 16).
