A fin tube heat exchanger (100) includes a plurality of fins (31) arranged in parallel and a heat transfer tube (21) configured to allow a medium to flow through the heat transfer tube to exchange heat with air. Each of the fins (31) is a corrugated fin formed to have a peak portion (34) at at least one position in an air flow direction, and has a tube surrounding portion (35 or 37) formed around the heat transfer tube (21), a first inclined portion (38) inclined with respect to the air flow direction to form the peak portion (34), a second inclined portion (39) connecting the tube surrounding portion (35) and the first inclined portion (38) to each other, and a slit (23) formed in the second inclined portion (39). |
