Abstract
A vibration device includes: a base substrate which is a first conductivity type semiconductor substrate; a lid substrate; a vibration element disposed between the base substrate and the lid substrate; a wiring disposed on a surface of the base substrate at the lid substrate side; and a coupling member that electrically couples the wiring and the vibration element to each other. The base substrate includes a second conductivity type well, which is different from the first conductivity type, and a first conductivity type first contact area that is disposed in the well and that has a first contact surface which is a part of the surface. The wiring and the coupling member are in contact with the first contact surface, and are electrically coupled to each other via the first contact area.
