A hollow spring member and hollow spring member production method can be provided, which can save the time and energy necessary for carburization, thus requiring no dedicated carburizing furnace or the like for carburization, and further can make the interior space of a steel tube a rust-prevention atmosphere. A hollow stabilizer (10) for a vehicle includes a steel tube (10P) sealed at one end and another end (11, 12) thereof and a carburizing gas sealed in the interior space (13) of the steel tube (10P).
