Abstract: A heat exchanger 100 includes: an inner cylinder 10 through which a first fluid can flow, the inner cylinder 10 being configured to be capable of housing a heat recovery member 40; an outer cylinder 20 disposed so as to be spaced on a radially outer side of the inner cylinder 10 such that a second fluid can flow between the outer cylinder 20 and the inner cylinder 10; and an intermediate cylinder 30 disposed between the inner cylinder 10 and the outer cylinder 20, the intermediate cylinder 30 partitioning a flow path for the second fluid into an inner flow path 31b and an outer flow path 31a. In the heat exchanger, the intermediate cylinder 30 includes communication holes 32 that are communicated in a radial direction, and the communication holes 32 are provided in an axial direction of the intermediate cylinder 30.
