The invention provides an oscillator which is unlikely to transfer external heat to a vibration element and has stable frequency characteristics. The oscillator includes: an outer package; an inner package accommodated in the outer package and fixed to the outer package via a heat insulating member; a vibration element accommodated in the inner package; a temperature sensor; a first circuit element accommodated in the inner package and including an oscillation circuit configured to oscillate the vibration element and generate a temperature-compensated oscillation signal based on the temperature sensor; and a second circuit element fixed to the outer package and including a frequency control circuit configured to control a frequency of the oscillation signal. 振荡器。本发明提供一种外部的热不易传递到振动元件，具有稳定的频率特性的振荡器。振荡器具有：外侧封装；内侧封装，其收纳在所述外侧封装中，隔着隔热部件固定于所述外侧封装；振动元件，其收纳在所述内侧封装中；温度传感器；第1电路元件，其包含振荡电路，该振荡电路使所述振动元件振荡，生成基于所述温度传感器进行温度补偿后的振荡信号，该第1电路元件收纳在所述内侧封装中；以及第2电路元件，其固定于所述外侧封装，包含控制所述振荡信号的频率的频率控制电路。
