摘要： To provide a method for manufacturing a spring having a painted surface, the method being capable of reducing a time period required for performing a paint baking process and low temperature annealing process while performing these processes at the same time. This manufacturing method has a step of heating the spring to a predetermined temperature (S12) and a step of spraying paint onto a surface of the spring and baking the paint while cooling the heated spring in accordance with a predetermined cooling pattern (S 14, S16). The predetermined temperature in the heating step and the cooling pattern obtained in the painting step are set such that a predetermined low temperature annealing process is performed on the spring in the heating and painting steps.
