Abstract:
1. An acceleration sensing device, comprising: an acceleration sensor chip including a movable sensing member, a frame member having a principal surface and a rear surface opposite to the principal surface wherein the frame member surrounds the movable sensing member, and a supporting member coupled between the movable sensing member and the frame member, wherein the supporting member includes a detecting element which detects displacement of the movable sensing member; a supporting frame member disposed on the principal surface of the frame member so as to surround the movable sensing member; a veiling member disposed on the supporting frame member so as to cover the movable sensing member; a resin film disposed on the principal surface of the frame member so as to seal the veiling member; a base substrate disposed on the rear surface of the frame member so as to cover the movable sensing member; a plurality of internal electrodes disposed at the principal surface of the frame member and electrically connected to the detecting element, wherein the internal electrodes are arranged around the supporting frame member; and a plurality of external electrodes disposed at the principal surface of the frame member and electrically connected to the internal electrodes.
