PROBLEM TO BE SOLVED: To provide a thin-edged blade capable of applying high grade work even to a fragile material. SOLUTION: This thin-edged blade 10 is formed by dispersing a super abrasive grain 21 in a metal base material 11 with Cu-Sn, Co or Ni as a base, and cuts a cutting object by rotating the metal base material around the axis. A glass filler 25 having a shape of 0.9 or more in the aspect ratio expressed by the short side/the long side, is mixed in the metal base material. COPYRIGHT: (C)2011,JPO&INPIT
