PROBLEM TO BE SOLVED: To provide a heat exchanging element capable of improving a yield in a punching step.SOLUTION: Plural stages of flow passage formation frame members 2 punched from a flat plate-like corrugated raw material and having a hexagonal contour shape 14 is laminated in via a partition film, and a heat exchanging element exchanges heat of gas via the partition film. The flow passage formation frame member 2 in each stage comprises two flow passage formation frame member halves 6 whose contour shape can be re-arranged into a parallelogram and the hexagon 14. |
