A method for manufacturing a stretched polyvinylidene fluoride film which comprises forming a non-stretched polyvinylidene fluoride film from a polyvinylidene fluoride polymer having an inherent viscosity in the range of from 0.8 to 1.8 as determined in a dimethylformamide solution at a concentration of 0.4 g/100cc at a temperature of 30*C, said non-stretched film containing spherulites having a diameter of from 2 to 20 Mu , and stretching the resulting film at a temperature of from 140* to 165*C to a stretch magnification ranging from the spontaneous stretch magnification of said film to 1.8 times the spontaneous stretch magnification is disclosed.
