Abstract: The present invention relates to a method for manufacturing polyvinylidene fluoride piezoelectric fiber and, more particularly, to a method for manufacturing polyvinylidene fluoride piezoelectric fiber, comprising the steps of: manufacturing a spinning solution containing polyvinylidene fluoride; manufacturing piezoelectric fiber by a wet spinning of the manufactured spinning solution; and heat-treating the manufactured piezoelectric fiber. The present invention provides a method for manufacturing piezoelectric fiber that can improve piezoelectric properties greatly by maximizing the proportion of β-type crystals in the fiber.
