PROBLEM TO BE SOLVED: To provide a heat exchanger having a similar heat exchange performance and reducing a size by enhancing a heat transfer performance to reduce a distance between fins by coating the surfaces of the respective fins with a predetermined substance and more smoothly discharging condensate deposited on the surfaces of the fins. SOLUTION: The heat exchanger includes fins 10 arranged with a predetermined gap and passed with air; and a tube 6 installed between the fins and passing the fluid. The heat exchanger is constituted such that the fins 10 are arranged with one side surface subjected to a surface treatment by a hydrophilic substance and the other side surface subjected to a surface treatment by a water repellent substance opposed to each other with a predetermined gap.
