Abstract: An optical reflective element includes: a reflective body that rotationally oscillates about a first rotational axis; a first connector body that is coupled to the reflective body, and includes a groove portion provided in a position in which the first rotational axis is located; a first vibration body that is disposed in a direction intersecting the first rotational axis, and is coupled to a proximal end portion of the first connector body; a second vibration body that is disposed on a side opposite the first vibration body; a first driving body that causes the first vibration body to rotate; a second driving body that is coupled to the second vibration body; and a second connector body that connects the first vibration body and the second vibration body in a manner that allows the first vibration body and the second vibration body to vibrate.

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.
