ータ。[Claims for Utility Model Registration] 1. One longitudinal end of a transparent second rectangular plate 14 is fixed to one longitudinal end of a first rectangular plate 12 that produces a piezoelectric effect, and an alternating current voltage is applied to the first rectangular plate. A stress plate modulator that vibrates the first rectangular plate and transmits longitudinal waves of the vibration to the second rectangular plate to modulate light transmitted through the second rectangular plate. A first rod member having a coefficient of thermal expansion substantially the same as that of the first rectangular plate is coated with an adhesive 40 that becomes rubber-like on one side in the width direction corresponding to the point P where the longitudinal displacement of the first rectangular plate 12 becomes 0. 42 is glued with its longitudinal direction perpendicular to the longitudinal direction of the first rectangular plate, and the width direction corresponding to the point Q where the longitudinal displacement of the second rectangular plate 14 becomes 0 during the vibration. A second rod member 46 having a thermal expansion coefficient substantially the same as that of the second rectangular plate is attached to one side using an adhesive 44 that becomes rubber-like, and its longitudinal direction is perpendicular to the longitudinal direction of the first rectangular plate. grooves 50 and 52 are formed in the bottom plate 48 corresponding to the first and second rod members, the bottom plate is arranged to be inclined with respect to a horizontal plane, and the first and second rod members are placed in the grooves. A stress plate modulator characterized in that the first and second rectangular plates are supported by the bottom plate by inserting a rod member. 2 The adhesives 40 and 44 have a thickness of 0.3 to 0.
．． The stress plate modulator according to claim 1, characterized in that the stress plate modulator has a width of 7 mm and a width of 2.0 to 3.0 mm.
