Summary:PROBLEM TO BE SOLVED: To obtain a good heat exchange performance by preventing an increase in a ventilating resistance according to a deformation of a fin by increasing a strength of the fin while increasing a fin surface area in contact with the air, and assuring a predetermined air volume. SOLUTION: In the heat transfer apparatus comprising a heat transfer tube, a flat bottom flange 2, and a fin portion (gill-like winding fin F1) for forming a gill-like fin 1 by winding it on the tube; tops 1a of the fins 1 are continued, bottoms are folded at right and left in a shape for supporting the gill-like fins 1 at right and left positions of the flange 2 formed by folding the bottom to the right and left, and the tops 1a of the fins are formed in a curved surface.
