PROBLEM TO BE SOLVED: To provide a low-noise crystal oscillator for supplying a high-grade oscillation output by reducing the noise. SOLUTION: The crystal oscillator for outputting the oscillation output from a drive electrode formed on both the main surfaces of a crystal piece and connected to an oscillation circuit and an output electrode, formed on at least one of the main surfaces to be apart from and electrically connected to the drive electrode, is configured so that the oscillation output can be outputted from the collector side of a buffer amplifier, by connecting the output electrode to the emitter side of the buffer amplifier whose base is grounded.
