Abstract: A piezoelectric drive element includes: a movable part; a pair of piezoelectric drive parts each connected at one end portion thereof to the movable part and configured to rotate the movable part about at least a rotation axis; and a fixing part to which end portions of the piezoelectric drive parts are connected. The pair of piezoelectric drive parts are aligned in a direction along the rotation axis with the movable part located therebetween, a width of the movable part is narrower than a width of each of the pair of piezoelectric drive parts in a plan view, and the fixing part is placed in a gap region that is outside the movable part and that is located between the pair of piezoelectric drive parts in a plan view.

Abstract: An inertial force sensor includes a detecting device which detects an inertial force, the detecting device having a first orthogonal arm and a supporting portion, the first orthogonal arm having a first arm and a second arm fixed in a substantially orthogonal direction, and the supporting portion supporting the first arm. The second arm has a folding portion. In this configuration, there is provided a small inertial force sensor which realizes detection of a plurality of different inertial forces and detection of inertial forces of a plurality of detection axes.

Abstract: A light control system includes an optical reflection element and a controller. The optical reflection element includes: a reflector; and a first swing portion and a second swing portion disposed at respective one of positions sandwiching the reflector. Each of the first swing portion and the second swing portion includes: a first connection portion coupled to the reflector; a first vibration portion; a second vibration portion; a first drive portion; a second drive portion; and a second connection portion that connects the first and second vibration portions to a base. The controller causes the first and second drive portions of the first swing portion to vibrate in the same phase, and causes the first and second drive portions of the second swing portion to vibrate in the same phase but in the opposite phase to the first swing portion.
