PROBLEM TO BE SOLVED: To provide a heat exchanger improved in heat exchanging efficiency. SOLUTION: This heat exchanger 210 exchanges heat between a first fluid flowing between a plurality of fins 212 of plate shape arranged at predetermined spaces h, and a second fluid flowing in heat exchanger tubes 214 passing through the plurality of fins 212. A nano-porous layer is formed at least at a part of the surface of the fin 212 or an internal wall of the heat exchanger tube 214. COPYRIGHT: (C)2006,JPO&NCIPI
