[0015] With such a configuration as above, the heat transfer surface of the heat transfer member has very low wettability with an ultralow surface energy. [0016] Therefore, the heat transfer surface of the heat transfer member that is a condensation heat transfer surface is close to the ideal drop condensation surface, which provides a good heat exchange efficiency.
