    Abstract: A cutting blade detecting mechanism is provided in a cutting apparatus including a chuck table for holding a workpiece and a cutting blade having an annular cutting edge for cutting the workpiece held on the chuck table while the workpiece is being cutting-fed in an X-axis direction. The cutting blade detecting mechanism has a blade detecting unit configured to detect the state of the cutting edge of the cutting blade. The blade detecting unit includes an image capturing unit configured to capture an image of the cutting edge in the X-axis direction, a light emitter disposed in a position opposite the image capturing unit and facing the cutting edge, and a decision unit configured to determine the state of the shape of a tip end of the cutting edge from the image of the cutting edge which has been captured by the image capturing unit.
