Title:
VIBRATING ELEMENT, RESONATOR, ELECTRONIC DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/027381
Kind Code:
A1
Abstract:
The present invention achieves a high-frequency miniature vibrating element for which the CI value is small and which suppresses frequency spurs in the vicinity with a fundamental wave. A piezoelectric vibrating element (1) is provided with a piezoelectric substrate (10) having a rectangular vibrating area (12) and a supporting portion (13), exciting electrodes (25a and 25b), and lead electrodes (27a and 27b). The supporting portion (13) is provided with a first supporting portion (14), a second supporting portion (15), and a third supporting portion (16). The second supporting portion (15) is provided with at least one slit (20). The exciting electrodes (25a and 25b) and the lead electrodes (27a and 27b) are configured so as to have differing electrode materials and film thicknesses.
