Disclosed is an air conditioner coated by the coating composition to the resin-made components where due formation occurs upon the cooling operation, provides the antifouling performance against various stains, restrains enlargement of droplet, and provides an excellent long-term durability (sticking property and peeling off property) all at the same time. The air conditioner of the present embodiment forms a coating film 103 to surfaces of resin-made components and resin-made components installed to a rear flow side of the heat exchanger, includes the silica ultrafine particles 101 and the fluororesin particles 102, and provides, within the coating film 103, a silica film 104 comprising the silica ultrafine particles and the fluororesin particles 102 partially exposed from a surface of the silica film 104 in dots, and an exposed area of the silica film 104 is greater than an exposed area of the fluororesin particles 102.
