摘要

The blade of a surgical knife of the present invention is formed by subjecting a single-crystal silicon wafer in which the orientation of the polished surface is 110 or 100 to crystal anisotropic etching. The blade has an edge as a higher-order surface of crystal anisotropic etching, and the edge slopes at a sharp angle in relation to the polished surface. Therefore, the surgical knife of the present invention which is made of single-crystal silicon, has good sharpness, reduces variability in sharpness quality, has high productivity at low cost, and is practical.
