PURPOSE:To cut the body of a long life and hard one of a sapphire and so on by forming diamond film by CVD at the tip blade part. CONSTITUTION:A CVD diamond film 2 is formed by a CVD method on the surface of a plate like base material 1 consisting of a plastic or nickel, stainless steel or tungsten, carbide and so on, and the desired dicing saw is obtained. This tip blade is not necessarily formed in a discoid shape, a CVD diamond film 2 may be formed only on one main face of the base material 1, also the tip blade part may be laminated in multiple-layer. |
