Claim 12:
13. A method of manufacturing a plurality of types of oscillators including a first oscillator and a second oscillator, the method comprising:
housing a first resonator and a first integrated circuit device configured to oscillate the first resonator in a first container to manufacture the first oscillator; and
housing a second resonator and a second integrated circuit device configured to oscillate the second resonator in a second container to manufacture the second oscillator, wherein
the first integrated circuit device includes a first oscillation circuit configured to oscillate the first resonator to output a first oscillation signal, and no PLL circuit,
the second integrated circuit device includes a second oscillation circuit configured to oscillate the second resonator to output a second oscillation signal, and a PLL circuit to which the second oscillation signal is input, and which is configured to output a third oscillation signal,
the first integrated circuit device and the second integrated circuit device are same in size as each other.
