Claim Text:
1. A method for manufacturing a heat exchanger in which particles of adsorbent expanded by absorbing moisture and contracted by dissipating moisture are supported on at least a surface of a fin of a heat exchanger body, the method comprising: preparing a slurry in which a binder and the adsorbent in a contracted state disperse in a solvent containing ethanol as a main component, the slurry being formed by mixing the adsorbent in a powder state, water-based resin containing the binder, water, and the solvent together; applying the slurry to the at least the surface of the fin of the heat exchanger body; and drying the slurry, thereby forming an adsorbent layer containing the adsorbent on the at least the surface of the fin of the heat exchanger body, wherein the slurry contains water of 10-40 parts by mass for the adsorbent of 100 parts by mass, and a mass of the ethanol contained in the slurry is greater than a mass of each of the adsorbent, the binder and the water that are contained in the slurry.
