Abstract
A crystal oscillator is configured by accommodating a crystal blank that functions as a crystal unit and an IC chip that includes at least an oscillator circuit using the crystal blank into a container in an integrated manner. In the IC chip, the oscillator circuit is connected to the crystal unit via a pair of crystal connecting terminals, an output from the oscillator circuit is supplied to a plurality of output buffers. In relation to the crystal connecting terminal having a phase opposite to that of an output from the on/off controllable output buffer, an output terminal of this output buffer is disposed farther than an output terminal of the output buffer that is not subjected to the on/off control.
