PROBLEM TO BE SOLVED: To provide a temperature-compensated quartz oscillation circuit capable of confirming operation of a temperature compensation circuit in a short time without increasing the number of terminals. SOLUTION: The temperature-compensated quartz oscillation circuit comprises: providing a switch element 160 for connecting an input terminal of a temperature compensation circuit 130 with a data terminal 106 of an existent control circuit 150; and inputting, from the data terminal 106 of the control circuit 150 to the temperature compensation circuit 130, a pseudo signal of an output signal from a temperature sensor 140.
