An optical element manufacturing method comprises steps of: preparing a wafer having opposite surfaces the extension of which intersecting each other at a predetermined angle; irradiating the wafer with a laser beam to form fringes on the wafer and displaying the fringes on a display for observation; determining cutting lines on the wafer with reference to the positions of the fringes; and cutting the wafer along the cutting lines to obtain a plurality of optical elements. By using method mentioned above, a nonlinear optical crystal element having an inclined plane can be produced in quantities.
