<P>PROBLEM TO BE SOLVED: To provide a groove processing tool that can perform groove processing by reciprocal movement, and is small in variation in the width of a blade caused by abrasion, and achieved in long lifetime. <P>SOLUTION: The groove processing tool 2 is held by a holder 17 and moved on a substrate reciprocally and relatively together with the holder 17 to form a groove at the substrate, and includes a tool body 36 held by the holder 17 and a cutting edge 37. The cutting edge 37 has a first blade 38a formed at a tip of the tool body 36 and formed at a top on a forward-movement side in a moving direction, and a second blade 38b formed at a top on a backward-movement side, and the first blade 38a and the second blade 38b successively adjoin. <P>COPYRIGHT: (C)2013,JPO&INPIT |
