PROBLEM TO BE SOLVED: To highly accurately form a groove of a prescribed depth from a top face of a substrate in a workpiece having a laminate formed on the substrate.SOLUTION: A cutting method includes: a cutting mark formation step for allowing a cutting blade 42 having a prescribed outer diameter and rotating to cut at a depth from a laminate 12 side to a substrate 11 and forming a cutting mark 16 elongating in a length direction orthogonal to a thickness direction of the cutting blade 42 and having a substrate cutting mark 18 exposed in a laminate cutting mark 17 in a workpiece 10; a cutting depth calculation step for calculating a cutting depth of the cutting blade 42 into the substrate 11 on the basis of a distance L in the length direction of the substrate cutting mark 18 and the outer diameter of the cutting blade 42; and a cutting step for adjusting a tip height of the cutting blade 42 on the basis of the cutting depth into the substrate 11, positioning the cutting blade 42 so as to have a prescribed cutting depth in relation to the substrate 11 and cutting the workpiece 10. |
