Abstract

The present invention provides a heat exchanger which is imparted with high deodorizing properties in terms of cigarettes. A heat exchanger which has a hydrophilic coating film on the surface of a substrate that is formed from aluminum, and wherein the hydrophilic coating film is formed using a hydrophilizing agent that contains 0.8-1.8% by mass of a vanadium compound in terms of elemental vanadium, while containing 90% by mass or more of a resin which contains 38-40% by mass of a polyvinyl alcohol having an ethylene chain, 22-24% by mass of a radically polymerizable monomer having a carboxylic acid, 15-17% by mass of a radically polymerizable monomer represented by general formula and 22-24% by mass of a polyethylene glycol.
