PROBLEM TO BE SOLVED: To provide a piezoelectric oscillator capable of contributing to miniaturization of the entire structure and being operated stably at all times. SOLUTION: The piezoelectric oscillator is configured in such a way that a rectangular container accommodating a piezoelectric vibration element in its inside is fixed on a rectangular packaging base on which a rectangular IC element for outputting an oscillation signal corresponding to an oscillation frequency of the piezoelectric vibration element is mounted via a plurality of spacer members to be disposed on four corners of the packaging base. In this oscillator, a metallic shielding member facing the side surface of the IC element is disposed along the external periphery of the packaging base between the container and the packaging base.
