PROBLEM TO BE SOLVED: To provide a cutting blade that can perform cutting to promote self-regenerating blade and excellently cut a surface film of a work-piece in particular.SOLUTION: A cutting blade (10) of the invention comprises an electrocast grindstone part in a circular ring-shape having abrasive-grains (12) fastened with a plating layer (11). In the plating layer are formed penetration holes (14) opened to both sides (11a and 11b) of the layer in a circular ring-shape and extended in a thickness direction and a plurality of non-penetration holes (15) opened to one of both sides and extended in the thickness direction. The cutting blade, even if amounts of cutting blade's wear increase during cutting due to the penetration hole and the non-penetration holes so that the surface film of the work-piece adheres to the blade, can promote a self-regenerating blade and also keep processing quality excellent.SELECTED DRAWING: Figure 2 【課題】自生発刃を促すよう切削することができ、特に被加工物の表面膜を良好に切削できるようにすること。【解決手段】本発明の切削ブレード（１０）は、めっき層（１１）で砥粒（１２）を固定した円環形状の電鋳砥石部を備えている。めっき層には、円環形状の両側面（１１ａ、１１ｂ）に開口して厚さ方向に伸長する貫通孔（１４）と、両側面の一方に開口して厚さ方向に伸長する非貫通孔（１５）が複数形成される。切削ブレードは、貫通孔及び非貫通孔によって切削中における消耗量が多くなり、被加工物の表面膜が付着しても自生発刃を促進し、加工品質も良好に維持することができる。【選択図】図２
