A method for producing a stabilizer and a heating device allows the entirety of a hollow member to be uniformly heated to a temperature necessary for heat treatment, even in a case in which a cross section varying hollow member is used as the starting material. In a preliminary heating process, energizing heating is performed between electrodes 211A and 211B, which are arranged at cross section varying parts 114A and 115A at both ends of large cross sectional area part 113A. The large cross sectional area part 113A between the electrodes 211A and 211B can be heated. In an entire heating process, by performing energizing heating between electrodes 212 and 212, which are arranged at both ends of the cross section varying hollow member 100A, the entirety of the cross section varying hollow member 100A between the electrodes 212 and 212 can be heated. In the preliminary heating process, it is desirable to perform energization heating at a part having a cross sectional area ratio of 90 % or more with respect to the part having a large cross sectional area in the cross section varying part. |
