Abstract

PURPOSE:To make assembly work easier in an indicating device whose sound emitter is formed by fixing a transparent piezoelectric element to the inner surface of a transparent cover by forming the electrical connection of the piezoelectric element and a module of a resiliently contacting contactor. CONSTITUTION:On the inner surface of a cover glass 22, a transparent conductor layer 24 is coated, and to the center of this surface, the piezoelectric element 27 with transparent electrodes 25 and 26 on both sides in adhered. Between the transparent electrode 26 on the module side of the piezoelectric element 27 and a lead 18, an output conductive rubber 28 consisting of a resilient substance lies in a pressed state. And between the lead 18 and the transparent conductor layer 24, a grounding conductive rubber 29 lies in a pressed state. These conductive rubbers 28 and 29 are disposed outside the indicating region (l) of the cover glass 22 so that they cannot be seen from outside.
