PROBLEM TO BE SOLVED: To provide a fuel reformer capable of suppressing production cost and further improving the freedom degree of the formation position of a flow passage.SOLUTION: Provided is a fuel reformer 10 in which a reforming gas is reformed and a fuel gas is fed to a fuel battery, including: a cylindrical inner tube 11 storing a burner 14 inside; and a cylindrical outer tube 12 storing the inner tube 11 inside. The cylindrical space divided by the outer circumferential face of the inner tube 11 and the inner circumferential face of the outer tube 12 is made into an evaporation part 21, and the evaporation part 21 is disposed with a cylindrical water absorbable member 22 previously formed with a spiral flow passage 24. |
