摘要： A constant temperature oscillator which comprises: a crystal oscillator that is provided upright on a circuit board, and which comprises a plurality of lead wires extending out from a bottom face of an oscillator container in which a crystal piece is hermetically sealed; an oscillation element arranged on the circuit board and configuring an oscillation circuit in conjunction with the crystal oscillator; and a temperature control element including at least a heating chip resistance and a thermistor, arranged on the circuit board, and configuring a temperature control circuit that keeps an operating temperature of the crystal oscillator constant; and which is provided with a heat transfer plate between the heating chip resistance and the bottom face of the oscillator container, wherein, the heat transfer plate has a notch into which the heating chip resistance is fitted, and, a heat sink lies between the heat transfer plate and the heating chip resistance and closely contacts with them. In the constant temperature oscillator of the present invention, instead of a constant temperature oven having a large heat capacity which is conventionally used to keep constant temperature, the heat transfer plate made from a metal plate of a high heat transfer coefficient is adopted as a heat transfer structure. Thus, an object of the invention is to provide a constant temperature oscillator in which the heat efficiency is improved and that deals with thinning.
