Claim 10:
11. A flow path member for a heat exchanger, comprising:
an inner cylinder capable of housing a heat recovery member through which a first fluid can flow;
an outer cylinder having a feed port capable of feeding a second fluid and a discharge port capable of discharging the second fluid, the outer cylinder being disposed so as to be spaced on a radially outer side of the inner cylinder such that a flow path for the second fluid is formed between the outer cylinder and the inner cylinder;
a feed pipe connected to the feed port; and
a discharge pipe connected to the discharge port,
wherein the feed port and the discharge port are provided so as to be located in a distance of less than half the circumference of the outer cylinder in a circumferential direction,
wherein the feed port and the discharge port are located on the same circumference of the outer cylinder, and
wherein, in a cross section orthogonal to a flow direction of the first fluid, the inner cylinder is eccentric such that a central portion of the inner cylinder is located on the feed port and discharge port side relative to a central portion of the outer cylinder.
