In a method of manufacturing a hollow stabilizer, a pipe compressing step of compressing an electroseamed pipe in a temperature range of a hot state or a warm state so as to make a rate of a thickness with respect to an outer diameter between 18 and 35% is performed, and a forming step of forming the compressed electroseamed pipe in a stabilizer shape in a cold state is executed. Next, a step of applying a heat treatment to a half-finished stabilizer is performed, a shot peening step of impacting a shot on the half-finished stabilizer is performed, and a step of coating the half-finished stabilizer is performed.
