ABSTRACT:
A vibrator includes a vibrating member, and piezoelectric devices formed on both surfaces thereof. Supporting portions are formed at one end of the vibrating member with connecting portions provided therebetween. A weight is mounted to the other end of the vibrating member with other connecting portions provided therebetween. The supporting portions are fixed to a holding member having a concave portion. The hardness of the holding member is set lower than the hardness of the vibrating member. As the material for the holding member, it is preferable to use a vibration-absorbing material for efficiently absorbing vibrations leaking from the vibrating member.
