Abstract

PURPOSE:To make a connecting part invisible by adhering a transparent piezoelectric element to a transparent cover, extending a transparent electrode on the adhered side of the piezoelectric element to contact a case and connecting a transparent electrode on the other surface in the opaque region of the cover. CONSTITUTION:Transparent electrodes 19 and 20 are formed on both surfaces of the piezoelectric element 17, the element is adhered to the transparent cover 14 and the transparent electrode 19 is connected with a case 21 through a conductor layer 18 on the transparent cover 14. A contactor 22 contacts the transparent electrode 20 just under the opaque layer 15 of the transparent cover 14. By so doing, the connecting part connot be seen through the indicating region (l) of the transparent cover 14.
