Abstract
A vibration device includes a vibration body including a light-transmitting portion including first and second main surfaces opposing each other and a vibration portion that is continuous with the light-transmitting portion and vibrates with a main vibration together with the light-transmitting portion, and a piezoelectric vibrator fixed to the vibration portion. Localized vibration portions which generate a localized vibration different from the main vibration are provided at a position not overlapping with a center or approximate center of the light-transmitting portion.
