PROBLEM TO BE SOLVED: To provide a plate-fin type heat exchanger capable of realizing both a high heat exchanging efficiency and a high durability under a severe variation in thermal load required in a regenerating plate fin type heat exchanger used in a micro-gas turbine power generating device and having a configuration of superior mass-production characteristic. SOLUTION: Each of corrugation fins 4a, 4b is brazed to an outer surface of each of two tube plates 5a, 5a of low temperature fluid passages 5, respectively. The low temperature fluid passages 5 are arranged in a predetermined space in the container 3 storing cores 2 of a heat exchanger 1, thereby high temperature fluid passages 4 are formed by the corrugation fins 4a, 4b while being independent for every low temperature passages 5 and a thermal stress is released to improve durability remarkably and further element formation of the component parts can be attained, a brazing step can be decreased and its mass production characteristic can be improved.
