There is provided a heat conduction member inhibiting stress generation due to a thermal expansion difference while maintaining a thermally bonded state in a case of covering a cylindrical ceramic body with a metal pipe. A heat conduction member 10 includes: a cylindrical ceramic body 11, a metal pipe 12 on the outer periphery side of the cylindrical ceramic body 11, and an intermediate member 13 held between the cylindrical ceramic body 11 and the metal pipe 12. The cylindrical ceramic body 11 has passages passing through from one end face to the other end face and allowing the first fluid to flow therethrough. The intermediate member 13 is made of material having at least a part having a Young' s modulus of 150 Gpa or less. The first fluid is allowed to flow through the inside of the cylindrical ceramic body 11 while the second fluid having lower temperature than that of the first fluid is allowed to flow on the outer peripheral face 12h side of the metal pipe 12 to perform heat exchange between the first fluid and the second fluid. |
