PROBLEM TO BE SOLVED: To obtain a technology for producing a hydrogen-containing gas where stable reforming performance can be maintained for a long period of time by preventing problems such as the lowering of the catalytic activity or the like due to carbon deposition while realizing good reforming efficiency by steadily and stably starting the reforming reaction from the inlet site of a catalytic reaction chamber 5. SOLUTION: When performing a reforming reaction for obtaining a hydrogen-containing gas by a partial oxidation reaction and a steam reforming reaction by introducing a raw material gas f1 obtained by mixing steam and a hydrocarbon-based fuel after having been mixed with an oxygen-containing gas O into a catalytic reaction chamber 5, the temperature of a front chamber 9 of the catalytic reaction chamber 5 is kept at a temperature above T1 that is a lower limit temperature of the partial oxidation reaction, and lower than T2 that is a lower limit temperature of the steam reforming reaction, and also lower than T3 that is a self-ignition temperature of a mixed gas F2 at which the mixed gas F2 is self-ignited during its transferring time required to reach to the catalytic reaction chamber 5 from a mixing chamber 8.
