摘要：
An oscillation device includes: a piezoelectric vibrator (110) in which electrode layers (112, 113) are formed over top and bottom surfaces of a piezoelectric layer (111); a vibrating member (120) having at least atop surface to which the piezoelectric vibrator (110) is bonded; and a resin member (130) formed continuously in a circumferential direction over at least the outer side surface of the piezoelectric vibrator (110). Therefore, since it is possible to increase the working area of the piezoelectric vibrator, it is possible to realize both an increase in the sound pressure level of the output and miniaturization of the apparatus.
