PROBLEM TO BE SOLVED: To provide a manufacturing method of a temperature compensated crystal oscillator capable of obtaining a small-sized temperature compensated crystal oscillator with simple handling and excellent in the productivity. SOLUTION: The manufacturing method is characterized in that a mother board 15 including a board region A having a window 16 and a sacrificial marginal region B having a write control terminal 17 is prepared, then a package body 1 for containing therein a crystal vibrating element 5 is fitted to each board region A of the mother board 15 in a way of choking the window 16, an IC element 7 is mounted on the surface of the package body 1 located inside the window 16, temperature compensation data are given to the IC element 7 in each board region A via the write control terminal 17, a memory in the IC element 7 stores the temperature compensation data, and the mother board 15 is cut off along the outer circumference of each board region A to manufacture the temperature compensated crystal oscillator by cutting off each board region A from the sacrificial marginal region B.
