To provide a movable device which has the excellent detection accuracy of a swing angle.SOLUTION: A movable device comprises: first and second torsion beams having ends connected with each other via a movable part swinging around a first swing shaft; first and second drive beams connected to the other ends of the first and second torsion beams; a first support part supporting each of the first and second drive beams in a cantilever manner; first and second distortion resistances arranged in the first drive beam; third and fourth distortion resistances arranged in the second drive beam; and a detection part outputting angular information around the first swing shaft based on each resistance value of the first to fourth distortion resistances. The first distortion resistance is arranged on the free end side of the first drive beam with respect to the first swing shaft and the third distortion resistance is arranged on the free end side of the second drive beam with respect to the first swing shaft. The second distortion resistance is arranged on any of the fixed and free ends of the first drive beam with respect to the first swing shaft and the fourth distortion resistance is arranged on any of the fixed and free ends of the second drive beam with respect to the first swing shaft. A distance between the first distortion resistance and the first swing shaft is longer than a distance between the second distortion resistance and the first swing shaft. A distance between the third distortion resistance and the first swing shaft is longer than a distance between the fourth distortion resistance and the first swing shaft.SELECTED DRAWING: Figure 4
