Provide a production method and production device of a hollow stabilizer making it possible to consecutively carry out carburization and quenching of a hollow stabilizer, save the time necessary for carburization and energy consumed by carburization, and requiring no dedicated carburizing furnace for the purpose of carburization. A hollow stabilizer production method of a hollow stabilizer used for a vehicle includes attaching a first mounting member (75) and a second mounting member (82) respectively to one end (101) and another end (102) of a formed steel tube (100) and heating the steel tube (100). The method includes feeding a carburizing gas into the interior space (103) of the heated steel tube (100) through the first mounting member (75), and collecting the air and/or the surplus carburizing gas from the interior space (103) through the second mounting member (82) to thereby carburize the steel tube inner surface (105). The method includes rapidly cooling the heated steel tube (100) to thereby quench the steel tube (100) continuously from the carburization.
