Abstract

A cutting apparatus includes a rotatable holding table having a rectangular holding surface, a cutting unit having a cutting blade mounted to a rotatable spindle, and a sensor unit detecting a tip of the cutting blade entering between a light projection section and a light reception section. The sensor unit has an upper end located to be lower than a lower end of the holding table in a Z direction and is located below the axis of the spindle or an extension region of the axis, and when short sides of the rectangular holding surface are set parallel to a Y direction, an upper side of the sensor unit is opened to allow the cutting blade to enter between the light projection section and the light reception section.
