A fin-and-tube type heat exchanger (HE) equipped with a plurality of plate fins aligned within a case (2) in the front-back direction of the case (2), and a heat transfer tube (3) that includes a plurality of linear tube body parts (30) passing through the plurality of plate fins. First and second plate fins (1A, 1B) aligned in the left-right width direction of the case (2) are provided as the plurality of plate fins. The heat transfer tube (3) has connecting tube body parts (31, 32) that connect the linear tube body parts (30) passing through each of the first and second plate fins (1A, 1B), and the heat transfer tube passes through the regions in which the first and second plate fins (1A, 1B) are arranged. |
