This invention provides a heat exchanger fin capable of improving heat transfer rate while preventing generation of heat bypass flow. The invention relates to a heat exchanger fin such as a louver fin 4 provided with a plurality louvers 5 arranged at certain intervals in the introduction direction X of air A, the louvers being formed by cutting and bending the heat exchanger fin so that the air A is passed while being guided by the louvers 5. The plurality of louvers 5 include louvers different in louver width, the louver width being defined by a length of the louver along which the heat medium passes, and the wide louver and the narrow louver are arranged alternatively. |
