A hollow stabilizer (1) has a tubular shape and is provided with: a torsion section (1a) that is provided to a vehicle and that extends in the vehicle width direction; an arm section (1b) that extends in the front-back direction of the vehicle; and bent sections (1c, 1c) that connect the torsion section (1a) and the arm section (1b). The hollow stabilizer (1) is characterized in that the hardness of the outer surface (1e) of the bent inner sides (1c1, 1c2) of the bent sections (1c, 1c) is 70% or more with respect to the hardness of the outer surface (1e) of the arm section (1b). |
