The invention discloses a manufacturing method of a stainless steel band for electronic film spring plates, in particular to a manufacturing method of a stainless steel band that is used for the procession of spring plates under switch buttons of electronic products. The manufacturing method is characterized by comprising the following steps in sequence: preparing materials, a first rolling, a first annealing, a first cleaning, a second rolling, a second annealing, a second cleaning, a third rolling, a third cleaning, relief annealing, straightening and tensioning and the like. The stainless steel band manufactured with the manufacturing method has high rigidity, yield strength and elasticity, and the electronic film spring plates processed by the stainless steel band have high quality andlong service life.
