Abstract
The micro-actuation element (X) includes a movable unit (), a frame () and a coupler () for connecting these, where the unit, the frame and the coupler are integrally formed in a material substrate having a multi-layer structure that consists of electroconductive layers (-), such as a core conduction layer (), and insulation layers () intervening between the electroconductive layers (-). The movable unit () includes a first structure originating in the core conduction layer (). The frame () includes a second structure originating in the core conduction layer (). The coupler () includes a plurality of electrically separated torsion bars () that originate in the core conduction layer () and are connected continuously to the first structure and the second structure.
