An evaporator (e.g., a small-sized high-efficiency evaporator) and a fuel reformer having the same. The evaporator has multi-stage structure (e.g., a four-stage disk structure), in which the respective disks are filled with fin structures. The first two disks through which exhaust gas passes and the second two disks through which water passes are stacked alternately with each other. Also, the first two disks are coupled with each other by a first pipe penetrating through one of the second two disks, and the second two disks are coupled with each other by a second pipe penetrating through one of the first two disks.
