PROBLEM TO BE SOLVED: To obtain a heat exchange which is not enlarged, a heat exchanger in which a device performance is not reduced, and a heat exchange in which a pressure resistant strength is not reduced.SOLUTION: The heat exchanger comprises at least a heat conduction member in which at least one first fluid flow passage in which a first fluid flows, at least one second fluid flow passage row where a plurality of second fluid flow passages in which a second fluid exchanging heat with the first fluid flows are provided in a row shape, and at least one third fluid flow passage in which the second fluid flows are formed at least. The second fluid flow passage and the third fluid flow passage are provided in such a manner that the closer to the first fluid flow passage the fluid flow passage becomes, the smaller a sectional area becomes, that the closer to the first fluid flow passage the fluid flow passage becomes, the wider an interval with the closest fluid flow passage belonging to the same row of fluid flow passages provided in the row shape becomes, or that the closer to the first fluid flow passage the fluid flow passage becomes, the smaller the sectional area becomes and the wider the interval with the closest fluid flow passage belonging to the same row of fluid flow passages provided in the row shape becomes.
