Abstract: A heat exchanger includes plural tubes, a first tank, and a second tank. Refrigerant flows in order of a first internal passage of the first tank, a first tube, the second tank, a second tube, and a second internal passage of the first tank. A channel forming portion is provided inside the second tank to form a refrigerant channel having a cross-sectional area smaller than that of an internal passage of the second tank in a cross-section orthogonal to a longitudinal direction of the second tank. The refrigerant channel is arranged so that a projection area of the refrigerant channel overlaps the tube when viewed in the longitudinal direction of the second tank.
