摘要：
A sharp-edged blade of the invention includes a circular thin-plate-shaped abrasive grain layer 3 in which abrasive grains 2 are held in a bond phase 1. An oxide film manufactured by a sol-gel method is formed on the surface of at least the bond phase 1 of the abrasive grain layer 3 as a first protective layer 4. A thick oxide film which has polycrystals and is structured such that a grain boundary layer composed of a glass layer does not exist at an interface substantially between the crystals is formed on the surface of the first protective layer 4 as a second protective layer 5.
