PROBLEM TO BE SOLVED: To improve a productivity of heat exchanger by a method wherein the number of component elements is reduced and an assembling of the component elements is facilitated. SOLUTION: A heat exchanging member is formed of a first paper member 10 having a moisture permeation characteristic formed in a corrugated shape in its width direction with both ends of the paper crushed in its longitudinal direction to form each of flat portions 10b, 10c. In addition, this heat exchanging member is comprised of a pair of second paper members 11, 12 forming each of header segments 11a, 12a to define a header part by a method wherein one end is overlapped on each of the flat portions 10b, 10c while being connected to each other and the other end is extended flat in a longitudinal direction. |
