Exemplary piezoelectric vibrating pieces have an excitation electrode and an extraction electrode having uniform thickness in the vibrating region to prevent unnecessary vibrations and degradation of vibration characteristics. An exemplary piezoelectric vibrating piece includes a vibrating portion having an excitation electrode of a first thickness (d1), an outer frame surrounding the vibrating portion with a gap therebetween, a joining portion connecting the vibrating portion and the outer frame, and an extraction electrode connected to the excitation electrode and extending on the vibrating portion, joining portion, and outer frame. The extraction electrode has the first thickness d1 throughout the vibrating portion and a second thickness (d2>d1) on the outer frame.
