The present invention addresses the problem of providing a cutting blade that satisfies both stable shape accuracy and workability. This flat blade-shaped cutting blade (1) has a flat base section (5), and a blade tip section (7), which serves as a cutting implementation section formed at the end of the base section. The cross-sectional shape of the blade tip section (7) in the thickness direction is such that the shortest distance between the point of intersection between two straight lines (9a, 9b) that lie along left and right blade surfaces, and the blade tip (11) is 1 μm to 10 μm. |
