Abstract

A heat exchanger includes a plurality of flat tubes each extending in a top-bottom direction with a flat external shape and each having a plurality of refrigerant flow paths in a form of through-holes; and a pair of headers connected to end portions of the plurality of flat tubes on both sides in the top-bottom direction and including respective L-bent portions each having an L shape in top view. The plurality of flat tubes are each shaped to have a major axis and a minor axis in a normal section taken to be normal to a tube-axis direction. At least one or two or more flat tubes included in the plurality of flat tubes and connected to the L-bent portions each have a wall thickness that increases toward two end portions in the normal section and decreases toward a central portion in the normal section, the two end portions and the central portion being located in a major-axis direction that is parallel to the major axis.
