Provided is an oscillator including a piezoelectric vibrator (10), a vibration member (20) that constrains the piezoelectric vibrator (10) on one surface thereof, an elastic member (40) that is provided on one surface of the vibration member (20) or the other surface opposite to one surface and provided so as to be located between edges of the piezoelectric vibrator (10) and the vibration member (20) when seen in a plan view, a fixing member (42) that is provided on one surface or the other surface of the vibration member (20) and provided so as to be located between the piezoelectric vibrator (10) and the elastic member (40) when seen in a plan view, and a supporting member (30) that supports the vibration member (20) through the elastic member (40) and the fixing member (42).
