Abstract
A vibration device includes a base, a vibrator disposed at the base, an annular resin element that is bonded to the base and surrounds the vibrator in a plan view, and a lid so disposed that the vibrator is sandwiched between the base and the lid. A first metal layer is disposed at a surface of the resin element, the surface facing the lid. A second metal layer is disposed at a surface of the lid, the surface facing the resin element. The vibrator is encapsulated by the base, the resin element, and the lid when the first metal layer and the second metal layer are bonded to each other.
