A fin for a heat exchanger of an air conditioning apparatus, the fin comprising: a base material; a hydrophilic layer; and a corrosion-resistant layer provided between the base material and the hydrophilic layer; a contact angle of a surface of the hydrophilic layer with water being no more than 50 degrees; and a water content of the hydrophilic layer per dm the water content being a value obtained by immersing a bottom end of the fin into 1 mm or more of water, recording a mass of the fin when immersed as an initial mass submerging the fin in a predetermined depth of water and leaving the fin submerged for fourteen hours, finding a difference between the initial mass and the mass measured thirty seconds after returning the fin to a position where the initial mass was measured, and dividing the difference by the surface area.
