Cutting blade and manufacturing method of cutting blade

Abstract

A cutting blade(2), which can cut an insulating film while suppressing exfoliation of the insulating film such as a Low-k film that is likely to be exfoliated upon cutting, is demanded. A cutting blade(2), that can meet this demand, has a binder(2b) and abrasive particles(2a), in which the abrasive particles(2a) are fixed by the binder(2b) at least part of which is glassy carbon.
