Flows through the plurality of tubes (11) near the refrigerant inlet pipe to reach the U-turn header (2). In the U-turn header (2), the refrigerant makes a U-turn while being stirred, and flows through the tube (11) of the upper refrigerant flow unit (1) to the upper header (5). Next, the refrigerant flows from the upper header (5) through the remaining tubes (11) of the upper refrigerant flow unit (1) toward the U-turn header (2), and then the U-turn header (2) makes a U-turn. Then, the remaining tubes (11) of the lower refrigerant flow unit (1) flow to the lower header (4) and flow out of the refrigerant outlet pipe (10) to the outside. Thus, while the refrigerant flows through each tube (11), heat exchange is performed with the air flowing in the direction of the arrow W through the air flow gap including the corrugated fin (12).
