<p>Disclosed is a heat exchanger for an air conditioner, which can reduce the adherence of a dust, a mold or a bacterium thereto. Specifically disclosed is an indoor heat exchanger (10) for an air conditioner (100), which comprises an aluminum material (50), a resin-made hydrophilic layer (70) and a stain repellent layer (80). The resin-made hydrophilic layer (70) is formed on the front surface of the aluminum material (50) and contains a water-soluble anti-bacterial and anti-mold agent (71). The stain repellent layer (80) is formed on the front surface of the resin-made hydrophilic layer (70) and contains a stain repellent agent whose binding ability to a floating contaminant in the air is higher than that to water.</p>
