A heat exchanger (1) comprises: a plurality of tubes (20) through which first fluid flows; and a corrugated fin (10) that increases the efficiency of heat exchange between the first fluid flowing inside the tubes and the second fluid flowing outside the tubes. The corrugated fin has a plurality of bent portions (12) that are joined to the tubes, and a fin body (13) that is disposed between the bent portion joined to one of adjacent tubes and the bent portion joined to the other of the adjacent tubes. A plurality of grooves (11) that extend from the bent portion joined to the one tube toward the bent portion joined to the other tube are formed on the surface of the fin body. At a point in at least one of the plurality of grooves between the bent portion joined to the one tube and the bent portion joined to the other tube, a raised portion (111) is provided which is raised from the bottom (110) of the groove toward the surface (10a) of the corrugated fin.
