<p><P>PROBLEM TO BE SOLVED: To provide a compact high-frequency piezoelectric vibration element that has a small CI value and suppresses nearby spurious frequencies while using a fundamental wave. <P>SOLUTION: A piezoelectric vibration element 1 includes: a piezoelectric substrate 10 that has a rectangular vibration region 12 and a support portion 13; excitation electrodes 25a and 25b; and lead electrodes 27a and 27b. The support portion 13 includes a first support portion 14, a second support portion 15, a third support portion 16, and a fourth support portion. The second support portion 15 has a second inclined portion 15b and a second support portion main body 15a. The second support portion 15 is provided with at least one slit 20. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
