A vibration device includes a light transmissive body, a first cylindrical body, a plate-shaped spring portion, a second cylindrical body, and a vibrating body. The light transmissive body includes a main body portion on an inner side of a portion supported by the first cylindrical body, and a protruding portion extending from the main body portion toward an outer circumference of the light transmissive body and protruding outward more than a portion supported by the first cylindrical body. A ratio between an equivalent mass calculated from a moment of inertia of the protruding portion and a weight of the main body portion is about 0.8 to about 1.2, and a resonant frequency of the light transmissive body is larger than a resonant frequency of the spring portion.
