Zusammenfassung:	PURPOSE:To surely execute the bending formation of a thin sheet without deformation, etc., related to a bend-forming method of the metallic thin sheet used for outer edge of an electric shaver with reciprocative edge, thin metallic spring sheet, thin metallic sheet member, etc. CONSTITUTION:After winding the thin sheet 2 around a winding core metal 1 estimating a spring back, the thin sheet 2 is fixed to this winding core metal 1 with a clip along the outer shape of the winding core metal 1. The winding core metal 1 is inserted between a rotary roller 4 stuck with a rubber 3 and a roller frame mold 5 to apply the pressurizing force and the movement in the rotating direction thereto.
