压电振动器及使用该压电振动器的振荡器
摘要：
在基底基板(2)形成的第一贯通电极(10a)与安装部(9)之间形成第一迂回电极(5a)，在盖基板(3)的基底基板(2)侧的表面形成第二迂回电极(5b)，将第一迂回电极(5a)和第二迂回电极(5b)，在安装部(9)附近利用第一连接部(7a)、而在第一贯通电极(10a)附近利用第二连接部(7b)分别电连接，从而降低迂回电极(5)的电阻。由此，在基底基板(2)表面设置的安装部(9)以悬臂状态安装压电振动片(4)，并且用盖基板(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)的电阻而防止振动性能的降低。
摘要（英）：

In a piezoelectric vibrator 1 in which a piezoelectric vibrating reed 4 is mounted on a mounting portion 9 installed on a surface of the base substrate 2 in a cantilevered state and the piezoelectric vibrating reed 4 is accommodated to be covered by a lid substrate 3, the resistance of a lead-out electrode 5 for supplying a drive power to the piezoelectric vibrating reed 4 is reduced, thereby preventing degradation of vibrating performance. A first lead-out electrode 5a is formed between a first through-electrode 10a and a mounting portion 9 formed on a base substrate 2, a second lead-out electrode 5b is formed on a surface of a lid substrate 3 on the base substrate side 2, the first and second lead-out electrodes 5b are electrically connected to the first and second connection portions 7a, 7b in the vicinities of the mounting portion 9 and the first through-electrode 10a, respectively, thereby reducing the resistance of the lead-out electrode 5.
