A synthetic quartz glass substrate for use in a microfluidic device, wherein a maximum value of a cyclic average power spectral density at a spatial frequency of 0.4 mm?1 or more and 100 mm?1 or less is 5.0×1015 nm4 or less, the maximum value being obtained by measuring any given region of 6.0 mm×6.0 mm on a surface of the synthetic quartz glass substrate with a white interferometer.

Abstract: A synthetic quartz glass substrate is machined by bringing a surface of the synthetic quartz glass substrate as the workpiece into contact with and superposing it on a surface of a protective member made of synthetic quartz glass to effect optical contact bonding of the workpiece and the protective member, and passing a cutting tool through the optical contact bonding surfaces. This machining process is able to effectively prevent the generation of microdefects at the cutting tool entry site and extraction site during a cutting operation. Moreover, a fixing agent is not used to join the workpiece and the protective member, and so productivity is high because there is no need for the application and later removal of a fixing agent.

Furthermore, light distribution without irradiation unevenness such as Lambertian reflection can also be achieved.
