Abstract:
A scribing wheel for scribing a brittle material-made substrate. Disc-shaped scribing-wheel base material in use is so designed that mid-portion of disc periphery has the largest diameter. Diamond film is formed on the periphery by a CVD method. The periphery is ground in the middle so that a plane including a circle defined by ridge line becomes perpendicular to the central axis of the scribing wheel.
