摘要： Plate-shaped fins 3 of a heat exchanger 4 each include, at circumferential portions thereof defining a notch 2 in which a heat transfer tube 1 having a flattened shape is disposed, fin collars 5 formed by being raised from the circumferential portions. Each of the fin collars 5 includes, in a position that faces a long axis side surface of the heat transfer tube 1, at least one reflare section 6 bent in a direction opposite to the side surface. At least one of the reflare sections 6 defining fin pitches between the adjoining plate-shaped fins 3 is formed so that a reflare tip portion 6b, which is a tip portion of the reflare section 6, is drawn apart from a contact side surface of the plate-shaped fin 3 with which the reflare section 6 comes into contact.
