Cutting method and manufacturing method for chip

A manufacturing method for a chip in which a workpiece is split to manufacture the chip, the manufacturing method comprising:

• holding the workpiece including a crystal structure having a c-axis inclined with respect to a perpendicular to a surface and a c-plane perpendicular to the c-axis;
• and
• cutting the workpiece along a planned cutting plane that is perpendicular to the surface and is inclined with respect to the c-plane by rotating a cutting blade having an annular cutting edge and making a tip portion of the cutting edge cut into the workpiece, wherein,
• in the cutting the workpiece, the workpiece is split along the planned cutting plane to manufacture the chip by making the tip portion cut into the workpiece in a state in which a force in such an orientation as to bring an angle formed by the planned cutting plane and the tip portion close to 0° acts on the cutting edge from the workpiece when the tip portion is made to cut into the workpiece.
