Abstract
A sensor includes an acceleration detector, an angular velocity detector, a driver, and first to fourth springs. Each detector includes a pair of fixed electrodes, a pair of movable electrodes, and a pair of supporting members for supporting the movable electrodes. The driver causes the supporting members to vibrate in opposite phases in a first direction. The first spring couples the supporting members of the acceleration detector and has elasticity in a second direction perpendicular to the first direction. The second spring couples the supporting members of the acceleration detector to a base and has elasticity in both directions. The third spring couples the supporting members of the acceleration detector to the supporting members of the angular velocity detector and has elasticity in both directions. The fourth spring couples the supporting members to the movable electrodes of the angular velocity detector and has elasticity in the second direction.
