PROBLEM TO BE SOLVED: To provide a heat conduction member where a crack or breakage is hard to occur to a cylindrical ceramic body.SOLUTION: A heat conduction member 10 includes: a cylindrical ceramic body 11 which has an outer peripheral wall provided on an outer periphery thereof and has a flow passage where a first fluid to be a heating body flows, the flow passage penetrating from one side end 2 to the another side end 2 of the cylindrical ceramic body 11; a metal pipe 12 having an annular corrugation part 15 which is fitted to an outer peripheral surface 7h of the outer peripheral wall of the cylindrical ceramic body 11 and encircles the outer periphery of the cylindrical ceramic body 11; and an intermediate material 13 joined to the cylindrical ceramic body 11 and the metal pipe 12 while it is put between the cylindrical ceramic body 11 and the metal pipe 12. In the metal pipe 12, the corrugation part 15 projects outward, there is a filler in a gap between an inner surface of the corrugation part 15 of the metal pipe 12 and the intermediate material 13, the first fluid flows inside the cylindrical ceramic body 11, a second fluid lower in temperature than the first fluid flows on an outer peripheral surface 12h side of the metal pipe 12, and heat exchange is performed between the first fluid and the second fluid. |
