摘要： PROBLEM TO BE SOLVED: To accurately control the attenuation of light even when increasing the attenuation. SOLUTION: In an MEMs actuator 100, a fixed electrode 100b and a movable electrode 100a are formed so that a distance between the fixed electrode 100b and the movable electrode 100a increases as an overlapping area between the fixed electrode 100b and the movable electrode 100a increases (as an electrostatic capacity increases).
