摘要： In an inner fin (2) that is inserted into a tube (4) and performs heat exchange, a plate is made up of a top part (10) that is in contact with the upper plate part of the tube, a bottom part (12) that is in contact with the lower plate part of the tube, and a wall plate part (14) that partitions a space between the top and bottom parts, and a channel having a concave-shaped cross section and a channel having an inverted concave-shaped cross section are alternately repeated as channels of the gas by a pair of the wall plate parts facing each other. The wall plate part for each of the channels has a shape in which the wall plate part is bent left and right in a serpentine shape and projected and recessed parts (20 and 22) thereof are alternately repeated and formed, and the recessed part (22) of the wall plate part is formed with a chevron-shaped part (24) made up of an upward slope part (28) that bulges in a direction of the wall plate part facing the wall plate part and ranges from a base part to the top part and a downward slope part (29) that passes downward from the top part to a neighboring base part.
