Zusammenfassung:	[Problem] To provide a vehicle arm component manufacturing method whereby the yield of a material can be further improved. [Solution] The present invention has: an expanding step (S05) for expanding the X-direction width of a workpiece from a first width (X1) to a second width (X2) by pressing, in the Z direction, a portion (P8) to be applied with pressure, said portion being provided within the surface of the workpiece (W); and a separating step (S06) for cutting down, from a material (M) to be machined, the workpiece the X-direction width of which has been expanded to the first width.
