Claim:
1. A heat exchanger comprising: a first fluid flow portion formed of a honeycomb structure having a plurality of cells partitioned by ceramic partition walls and surrounded by a ceramic continuous outer peripheral face, with the plurality of cells extending from one end face to another end face of the honeycomb structure in an axial direction to allow a heating medium as a first fluid to flow therein, and a second fluid flow portion formed of a casing containing the honeycomb structure therein, the casing having an inlet and an outlet for a second fluid, and the second fluid flowing on the ceramic continuous outer peripheral face of the honeycomb structure in direct contact with a metal plate configured to cover and thus be in direct contact with the entire outer peripheral face, the second fluid being in direct contact with the metal plate at least at the entire portion of the metal plate where the entire outer peripheral face of the honeycomb structure is held, so as to receive heat from the first fluid.
