Provided is a fin tube heat exchanger in which multiple stacked fins are formed into a particular shape so as to make the air flow between the fins smoother and which exhibits excellent heat transfer performance by increasing the ridge lines that are the lines of intersection between surfaces in order to enhance the heat transfer performance between the fins and the air flow. A fin tube heat exchanger wherein: stacked heat-transfer fins each have a wedge-shaped dent () on the upstream wind side and the downstream wind side of a fin collar (); the dent () is configured from a first ridge line () extending in the column direction in the upstream wind side and downstream wind side of the fin collar (), and two second ridge lines () which are arranged in the shape of a V and which derive from the vertex (P) of the first ridge line () and a ridge line () on the valley side extending in the step direction; and two V-shaped slanted planes are formed by means of the first ridge line () and the second ridge lines ().
