In the present invention, when installing a piezoelectric oscillation piece in a main package body, the spread of adhesive to an oscillation unit is mitigated by restricting the direction in which the adhesive spreads along the rear surface of the piezoelectric oscillation piece, and the CI value of the piezoelectric oscillation piece is prevented from worsening. A piezoelectric device package (10) has a main package body (10a) for holding the piezoelectric oscillation piece (50), and connective electrodes (23, 24) which are electrically connected to excitation electrodes (53, 54) formed on the piezoelectric oscillation piece (50) are provided in the main package body (10a). The connective electrodes (23, 24) are provided with cutouts (25, 26) formed in the oscillation part (51) side of the piezoelectric oscillation piece (50) held in the main package body (10a). |
