PROBLEM TO BE SOLVED: To provide a heat exchanger in which an entire structure is simple, no artificial error occurs at the time of its assembly, its manufacturing cost is less expensive, a low temperature fluid passage and a high temperature fluid passage are air-tightly closed, thicknesses of the low temperature fluid passage and the high temperature fluid passage can be optionally set and fluid resistance is not influenced by their pressure difference. ! SOLUTION: A plurality of spaced-apart and laminated wall plates 2 in a surface direction between the side plates 1 are held between the side plates 1 acting as heat insulation material, spacers are arranged among them, the plurality of spaced-apart and laminated wall plates 2 and the side plates 1 of heat insulation material are arranged at front and rear sides and the side plates 1 and the plurality of spaced-apart and laminated wall plates 2 are fastened with screws, resulting in that a connection of superior sealing characteristic can be attained.
