摘要： A scribing wheel having a long life with little wear at the blade even when used to scribe a substrate that is relatively hard, such as a ceramic substrate, which can create deep vertical cracks if necessary is provided. A number of grooves 13 are created with predetermined intervals at the blade 12 that is along the ridgeline of the wheel of which the outer diameter is within a range of 1 mm to 5 mm. The depth D of these grooves 13 is 25 μm or more and the length of the ridgeline 14 between grooves is 25 μm or more. It is preferable for the pitch P of the grooves 13 to be in a range from 50 μm to 200 μm.
