[Claims for Utility Model Registration] (1) A large number of wavy band parts housed in the space formed between the outer cylinder and the inner cylinder are half pitched with respect to the adjacent band parts. In the inner fin for a double-tube heat exchanger that is connected to each other in a staggered manner, the number of outer cylinder side protrusions that protrude toward the outer cylinder out of the plurality of band-shaped parts is in contact with the outer cylinder. An inner fin for a double-pipe heat exchanger, characterized in that the number of inner cylinder side protrusions protruding toward the inner cylinder side is larger than the number of the inner cylinder side protrusions that come into contact with the inner cylinder. (2) The outer cylinder-side protrusion and the inner cylinder-side protrusion formed on one side of the adjacent band-shaped parts are in contact with the outer cylinder and the inner cylinder, respectively, and the outer cylinder-side protrusion formed on the other band-shaped part is in contact with the outer cylinder and the inner cylinder, respectively. 2. The inner fin for a double-tube heat exchanger according to claim 1, wherein only the outer cylinder side protrusion contacts the outer cylinder. (3) The double pipe type according to claim 1, wherein among the outer cylinder side protrusions and the inner cylinder side protrusions formed on the band-shaped part, every other inner cylinder side protrusion comes into contact with the inner cylinder. Inner fin for heat exchanger.
