<P>PROBLEM TO BE SOLVED: To provide a cutting blade or the like, capable of lowering stress generated in a green sheet laminate in cutting and suppressing the occurrence of delamination of the laminate in cutting. <P>SOLUTION: The cutting blade cuts the green sheet laminate having a plurality of multilayer ceramic green sheets. In the cutting blade: the blade surface has first, second, and third regions arranged in order from the cutting edge toward the ridge; the first region has a first angle formed to the center line of the thickness direction of the cutting blade; the second region has a second angle which is smaller than the first angle formed to the center line; the third region has a third angle which is smaller than the second angle formed to the center line; arithmetic mean roughness Ra of the first, second, and third regions is ≤0.1 μm; and the distance from the crossing point of the extensions of the first and the third regions to the second region is ≤5 μm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
