<P>PROBLEM TO BE SOLVED: To provide a piezoelectric oscillator that receives a plurality of kinds of piezoelectric vibration elements in different sizes or different shapes while using a common package, and also is compatible with both a cantilever-supporting structure and a double-supporting structure, with respect to a piezoelectric oscillator having an IC component incorporated in the package of a piezoelectric vibrator. Ž<P>SOLUTION: The piezoelectric oscillator includes an insulated substrate 4, a piezoelectric vibrator 2 and the IC component accommodated in an IC component receiving recess. The insulated substrate includes: two projecting element mounting pads 10 and 11 disposed separately along a width direction eccentrically to one edge; a first pillow member 15 provided with a projecting conductive pad in the center, eccentric to another edge, in the width direction; and a second pillow member 20 provided with a projecting conductive pad in the center in the width direction in the center in a length direction, wherein an IC component receiving recess 25 is provided between the first pillow member and the second pillow member. The piezoelectric vibrator 2 has a piezoelectric vibrating element 30 mounted on the element mounting pads. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
