A heat exchanger (HE) comprises: a fin (F) that is configured so as to extend in a shortitudinal direction (D1) along an air flow direction (D0) and a longitudinal direction (D2) that intersects the air flow direction (D0); and a heat exchanger tube (P) that passes through the fin (F). The fin (F) includes a flat portion (SP) and a plurality of first mountain portions (MP1) and a plurality of second mountain portions (MP2) configured so as to protrude from the flat portion (SP). The plurality of first mountain portions (MP1) includes a first protrusion (C1) that is configured so as to curve downward along the longitudinal direction (D2) and a second protrusion (C2) that is configured so as to curve upward along the longitudinal direction (D2).
