Abstract
A micro-oscillation element includes a base frame, an oscillating portion, and a link portion connecting the base frame and the oscillating portion to each other. The oscillating portion has a movable functional portion, a first driving electrode connected to the movable functional portion, and a weight portion joined to the first driving electrode. The link portion defines an axis of the oscillating motion of the oscillating portion. The second driving electrode, fixed to the base frame, generates driving force for the oscillating motion in cooperation with the first driving electrode.
