Dicing Blade |
| 摘要 |
An object of the present invention is to provide a dicing blade which does not cause cracking and breaking even in a workpiece formed from a brittle material, and can stably perform cutting process in a ductile mode on the workpiece with high precision. A dicing blade 26 which performs the cutting process on the workpiece is integrally formed of a diamond sintered body 80 which is formed by sintering diamond abrasive grains 82 so as to have a discoid shape, and a content of the diamond abrasive grains 82 of the diamond sintered body 80 is 80 vol % or more. It is preferable that recessed parts which are formed on a surface of the diamond sintered body 80 are continuously provided in an outer circumferential part of the dicing blade 26 along a circumferential direction. |
