| 1. A heat exchanger comprising:
a flat tube that extends from a header, the flat tube being a multi-channel flat tube including at least one partition for
dividing inside of the flat tube into a plurality of parallel flow channels; and
fins that contact the flat tube, wherein at an end part of the flat tube that is attached to the header, the at least one
partition is in a contracted state where at least part of the at least one partition is deformed, and at other part of the
flat tube that is attached to the fins, the at least one partition extends almost straight and is expanded in minor axis direction
with respect to the end pan.
