Abstract:
1. A piezoelectric resonator having a piezoelectric element, the piezoelectric resonator comprising: a piezoelectric substrate that includes a vibration region and a thick section integrated with the vibration region, and the thick section having a thickness larger than a thickness of the vibration region; excitation electrodes respectively arranged on a front surface and a rear surface of the vibration region; and lead electrodes provided extending from the excitation electrodes onto the thick section, wherein the thick section includes an inclined section having a thickness increasing as the inclined section separates further away from one end edge connected to the vibration region toward other end edge; and a thick main body connected to the other end edge of the inclined section, a package that houses the piezoelectric element, and a slit is provided in the thick section, and the slit has a vacant inside space, and the slit is provided between the vibration region and a region where the thick section is supported by the package.
