    • To provide a highly stable crystal oscillator having increased thermal efficiency. The highly stable crystal oscillator comprises; a thermostat mainframe which maintains the temperature of a crystal resonator including a resonator container for sealing a crystal piece constant, an oscillating element which constitutes an oscillation circuit together with said crystal resonator, a temperature control element which controls the temperature inside of said thermostat mainframe, and a circuit board mounted with said thermostat mainframe, said oscillating element, and said temperature control element. The construction is such that a heat generating chip resistor and a highly heat sensitive element having a higher temperature dependency, among said oscillating element and said temperature control element, are arranged on one principal plane of said circuit board, and said heat generating chip resistor, said highly heat sensitive element, and said thermostat mainframe are directly heat bonded by a thermo-conductive material.
