A heat exchanger includes plate fin stacked body (4) configured by stacking plate fins (3) each having a flow channel through which a first fluid such as a refrigerant flows. Plate fin (3) includes a pair of plates brazed to each other, and the pair of plates is provided with the flow channel therebetween. Plate fin (3) is provided with tubular parts (13) each protruding to the outside of each of the pair of plates in portions of header region X connected to the flow channel of plate fin (3), and by fitting and brazing tubular parts (13) of adjacent plate fins (3) to each other, the portions of header regions X of adjacent plate fins (3) are coupled and fixed together.
