  • Piezoelectric device
    Patent number: 9735756
    Abstract: A piezoelectric device includes a piezoelectric vibrating piece and a base. The piezoelectric vibrating piece includes an excitation portion, a framing portion, a connecting portion, excitation electrodes, and extraction electrodes. The base includes a mounting terminal, a cutout portion formed on a side surface, and a cutout-portion electrode formed in the cutout portion. The cutout-portion electrode connects the mounting terminal to the extraction electrode. The extraction electrode includes a cutout-portion region connected to the cutout-portion electrode, an excitation-electrode connecting region connected to the excitation electrode, and an erosion preventing region disposed between the cutout-portion region and the excitation-electrode connecting region to prevent erosion by solder.
    Type: Grant
