This method for producing a hollow stabilizer includes a forming step in which a pipe material (IS) is subjected to bending treatment in order to form a product shape provided with bent sections (1c, 1c) and a hardening step in which the pipe material (IS) that has been subjected to bending treatment is subjected to hardening. The method for producing a hollow stabilizer is characterized in that in the hardening step, the steel pipe material (IS) is immersed in a cooling agent and cooling treatment is carried out by spraying the cooling agent onto the outer surface (1e) of the bent sections (1c).
