Abstract:
Provided are a method for manufacturing a stabilizer and a heating device, the method being able to suppress the occurrence of unevenness in the hardness of a curved portion of a semimanufactured product of the stabilizer and reduce the process time in a tempering process. In electric heating in a first heating step (step A), the temperature of an inside portion of a shoulder can be steeply increased to a temperature (
