Abstract:
Provided is an oscillator (100) including a piezoelectric body (70) that has a plurality of protrusions (72) on one surface thereof, a plurality of electrodes (80) that are respectively provided on the plurality of protrusions (72) so as to be separated from each other, and a plurality of electrodes (82) that are provided on the other surface opposite to the one surface of the piezoelectric body (70) so that each of the electrodes faces only one electrode (80). Thus, it is possible to prevent variation in acoustic characteristics from occurring. Therefore, the oscillator capable of improving the acoustic characteristics of an electronic device is provided.
