Abstract
An oscillator includes a piezoelectric vibrator (10), a vibrating member (20) which is larger than the piezoelectric vibrator (10) when seen in a plan view and restrains one surface of the piezoelectric vibrator (10), a vibrating member (25) which is larger than the piezoelectric vibrator (10) when seen in a plan view and restrains the other surface of the piezoelectric vibrator (10), an elastic member (30) which supports an edge of the surface of the vibrating member (20), which restrains the piezoelectric vibrator (10), and supports an edge of the surface of the vibrating member (25), which restrains the piezoelectric vibrator (10), and a supporting member (35) which is located around the elastic member (30) and supports the elastic member (30).
