Abstract
A vibration device that includes a vibration portion, a support portion connected to the vibration portion, a bending-vibrating portion connected to the support portion, and a frame-shaped base portion connected to the bending-vibration portion and disposed so as to surround the vibration portion. The base portion defines a slit that extends in a first direction crossing a second direction in which the support portion extends from the vibration portion, the slit defining first and second fixed ends of the bending-vibrating portion and which are continuous with the base portion. A length between a portion of the bending-vibrating portion connected to the support portion to one of the first and second fixed ends of the bending-vibrating portion is in a range of λ/8 to 3λ/8, where λ denotes a wavelength of a bending vibration corresponding to a frequency of a characteristic vibration of the vibration portion.
