Abstract
A vibration device includes a first substrate that includes a first surface and a second surface; a second substrate that includes a third surface and a fourth surface; an intermediate substrate that is disposed between the first substrate and the second substrate and that includes a vibration element, a frame surrounding the vibration element, and a coupler linking the vibration element and the frame; a conductive first joining member that is located between the frame and the first substrate and that joins the frame and the second surface; a conductive second joining member that is located between the frame and the second substrate and that joins the frame and the third surface; an internal electrode disposed on the first substrate; and a first conductive member that is disposed between the first substrate and the intermediate substrate and that electrically couples the vibration element and the internal electrode.
