Abstract

PURPOSE:To eliminate curving of the electric field applied by main electrodes and auxiliary electrodes, suppress spurious vibrations, increase Q value and improve vibration characteristics by providing auxliary electrodes to at least a part of the circumference of main electrodes along said electrides and connecting these by means of connecting electrodes.
