<p>To provide a piezoelectric device capable of achieving a sufficient impact resistance even when the product is reduced in size, a cellular phone system using the piezoelectric device, and electronic equipment using the piezoelectric device. A piezoelectric device includes a base substrate 31 constituting the bottom of the package; a framed vibrating reed 32 layered on the base substrate; and a lid 33 for airtightly sealing a space within the package, the lid being layered on the framed vibrating reed. The framed vibrating reed includes a frame 36 constituting a wall surrounding the space within the package; a base 38 having a predetermined width, which is integrally formed inside the frame; a plurality of vibrating arms 34, 35 that extend in parallel to each other from the base in one direction in the frame; first cutouts 21, 21 that are provided near the base ends of the vibrating arms in the base 38; and second cutouts 22, 22 formed at the joint between the base 38 and the frame. <IMAGE></p> |
