Abstract:
1. An electrostatic driving device comprising: a flexible thin film; a holding member, which holds the flexible thin film and allows the flexible thin film to bend; a function member disposed on the flexible thin film; a film-side facing electrode disposed on the flexible thin film; a base, which faces the holding member; a base-side facing electrode, which is disposed on the base and faces the film-side facing electrode; and a bonding spacer member, which is held between the holding member and base, bonds the holding member to the base, and holds an interval between the holding member and base at a predetermined interval so as to keep an electrode interval between the film-side facing electrode and base-side facing electrode at a predetermined interval; wherein the bonding spacer member includes a bonding member, which bonds the holding member and base, and rigid members, which have rigidity, and the rigid members keep the interval between the holding member and base at the predetermined interval and at least one of the bonding member and rigid members included in the bonding spacer member has conductivity, and the electrostatic driving device further comprising; a film-side connecting member, which is disposed on the holding member and electrically connects the film-side facing electrode to the bonding spacer member; a first external electrode that is prepared for the flexible thin film, the first external electrode being disposed on the base; and a base-side connecting member, which is disposed on the base and electrically connects the first external electrode to the bonding spacer member.
