压电振动器及使用该压电振动器的振荡器
摘要：
将在基底基板(2)的安装部(9)与第一贯通电极(10a)之间形成的第一迂回电极(5a)，形成在不与在压电振动片(4)的外表面形成的驱动用的第一及第二激振电极(6a、6b)重叠的周围的区域，从而减小第一迂回电极(5a)的电阻。从而，将压电振动片(4)以悬臂状态安装到基底基板(2)的表面设置的安装部(9)上，并且在用盖基板(3)以覆盖地收纳压电振动片(4)的压电振动器(1)中，减小对压电振动片(4)提供驱动电力的迂回电极(5)的电阻，防止振动性能降低。
摘要（英）：

A first lead-out electrode formed between a mounting portion of a base substrate and a first through-electrode is formed in a peripheral region so as not to overlap with first and second excitation electrodes formed on outer surfaces of a piezoelectric vibrating reed for driving, thereby reducing the resistance of the first lead-out electrode. Thereby, in a piezoelectric vibrator in which the piezoelectric vibrating reed is mounted on the mounting portion installed on a surface of the base substrate in a cantilevered state and the piezoelectric vibrating reed is accommodated to be covered by a lid substrate, the resistance of a lead-out electrode for supplying a drive power to the piezoelectric vibrating reed is reduced, thereby preventing degradation of vibrating performance.
