A piezoelectric oscillator includes: a piezoelectric resonator including a container, the container containing a piezoelectric resonator element: and a semiconductor device including an oscillation circuit for vibrating the piezoelectric resonator. The semiconductor device is bonded to a surface of the container. The container has an external coupling terminal and a cut-off part, the external coupling terminal being coupled to the semiconductor device, the cut-off part being disposed on a side surface of the container. The external coupling terminal is disposed in an area of the container, the area being opposed to the semiconductor device, and in the cut-off part. The semiconductor device has a coupling terminal on a surface thereof, the surface being opposed to the container. The coupling terminal of the semiconductor device and the external coupling terminal of the container are coupled with a conductive material.
