Abstract:
A micro-electro-mechanical-system resonator, includes: a substrate; a fixed electrode formed on the substrate; and a movable electrode, arranged facing the fixed electrode and driven by an electrostatic attracting force or an electrostatic repulsion force that acts on a gap between the fixed electrode and the movable electrode. An internal surface of a support beam of the movable electrode facing the fixed electrode has an inclined surface.
