ABSTRACT:
A piezoelectric device includes a base substrate constituting the bottom of the package; a framed resonator element layered on the base substrate; and a lid for hermetically sealing a space within the package, the lid being layered on the framed resonator element. The framed resonator element includes a frame constituting a wall surrounding the space within the package; a base having a predetermined width, which is integrally formed inside the frame; a plurality of resonating arms that extend in parallel to each other from the base in one direction in the frame; first cutouts that are provided near the base ends of the resonating arms in the base; and second cutouts formed at the joint between the base and the frame.
