A semiconductor wafer 1 has first scribe lines 31 in two mutually perpendicular directions which have a first width and divide the semiconductor wafer 1 into a plurality of areas; second scribe lines 32 which have a second width smaller than the first width and divide the area into a plurality of semiconductor chip areas 2; an electrode pad 5 formed along the edge of the semiconductor chip area 2; and a metal-containing accessory pattern 4 disposed in the scribe lines. In the second scribe lines 32, the accessory pattern 4 is absent in at least the outermost surface in an area adjacent to the edge having the electrode pad 5 in the chip area 2. |
