    Abstract: An electromechanical resonator and a manufacturing method thereof are provided to form a vibrator through a fixed electrode and a gap and to form a large region and a narrow region in the gap for obtaining high mechanical strength. An electromechanical resonator comprises a resonating part having a fixed electrode(107) and a vibrator(109) formed through the fixed electrode and a gap. The gap includes first and second regions(113,111). The second region is large enough to ignore capacitance between the fixed electrode and the vibrator. The vibrator has air gaps. The air gaps have a large gap and a narrow gap. Maximum electrostatic force is generated at the narrow gap between the vibrator and the fixed electrode. A first insulating layer(103) is formed on a material substrate(101).
