A first objective of the present invention is to provide a more productive method of manufacturing optical devices that minimizes processing distortion, maintains optical characteristics satisfactorily, and promotes smallness. A second objective thereof is to provide a method of manufacturing optical devices that prevents the occurrence of fine dust and maintains the optical characteristics satisfactorily. A third objective thereof is to provide a method of manufacturing optical devices of a multi-layer configuration that are obtained by applying a scribing/cutting method. A method of manufacturing optical devices in accordance with the present invention, wherein an optical wafer having surfaces polished to a mirror finish is divided into a plurality of optical chips, is provided with a first step of providing hairline cracks by a diamond blade edge in one main surface of the optical wafer and a third step of applying pressure along the hairline cracks after the first step, to divide the optical wafer into the plurality of optical chips.
