Abstract
PURPOSE:To prevent a main surface from being flawed at the time of ultrasonic cleaning, by forming a groove bein parallel to an edge a very small distance from the edge of both main surfaces of a quartz double refraction plate. CONSTITUTION:A groove 7 being parallel to an edge 5 is formed in a position with a very small distance from the edge 5 of both main surfaces 2, 2' of a quartz double refraction plate 1. At the time of ultrasonic cleaning, the quartz double refraction plate 1 is supported by a cleaning jig 3 by utilizing the groove 7. In this way, it is prevented that the main surfaces 2, 2' are flawed uselessly.
