Abstract
A vibrating device includes a dome-shaped cover, a cylindrical or substantially cylindrical vibrating body, and a piezoelectric element. The dome-shaped cover is disposed so as to include a detection field of an optical detector element, and the cylindrical or substantially cylindrical vibrating body is fixed to the cover. The piezoelectric element is fixed to the vibrating body and vibrates the cover via the vibrating body. The vibrating body includes a cylinder portion, a first connection portion connected to a first end portion of the cylinder portion, a first ring-shaped portion connected to the first connection portion at a position near the cover, a second connection portion connected to a second end portion of the cylinder portion, and a second ring-shaped portion connected to the second connection portion at a position opposite to a surface to which the cylinder portion is connected.
