A heat exchanger includes tubes and a tank. The tubes extend in a first direction, and are stacked in a second direction. The tank has a tube insertion plate part, and is arranged at an end portion of the tubes. The tube insertion plate part has tube holes in which the tubes are inserted, and ribs extending in a third direction that is approximately perpendicular to the first direction and the second direction. The tube hole has end portions in the third direction. The rib are arranged to overlap with the end portion of the tube hole in the second direction, and to provide a deformable part to be deformable in the first direction. The deformable part is located in the tube insertion plate part outside of the ribs in the third direction.
