PROBLEM TO BE SOLVED: To provide a temperature-compensated piezoelectric oscillator capable of temperature compensation with high accuracy, by eliminating the difference between the ambient temperature of a piezoelectric vibrating element and the temperature sensed by a temperature sensor element. SOLUTION: The temperature compensated piezoelectric oscillator is provided with a container body constituted of a substrate, a first frame which is integrally provided on one principal surface of the substrate and forms a first recessed part, and a second frame which is integrally provided on another principal surface of the substrate and forms a second recessed part; a piezoelectric vibrating element mounted in the first recessed part; a first integrated circuit element; a second integrated circuit element mounted in the second recessed part; and a cover which air-tightly seals the first recessed part, wherein the first integrated circuit element comprises a temperature sensor and an oscillation circuit, and the second integrated circuit element comprises a temperature compensation circuit. Furthermore, the temperature compensated piezoelectric oscillator has a step which is provided to the substrate, within the first recessed part, and the first integrated circuit element is mounted in the step.
