After cutting into a substantially predetermined shape with small pitches using an NC machine tool, the uncut peaks remaining between the cut locations are polished to form a substantially mirror-like molded surface. In a mold for drawing a sheet metal along the forming surface by press working, a hardened surface hardened by shot peening is provided at least at a portion of the forming surface that generates a tensile load on the sheet metal during drawing. A drawing mold characterized by: 2. The drawing mold according to claim 1, wherein the hardness of the hardened surface is 25 to 35% higher than that of a portion of the molding surface other than the hardened surface.
