Abstract
A gyro sensor includes: a substrate; a first drive section; and a first detection section and a second detection section that detect angular velocity. The first detection section includes a first movable body including a first movable electrode that vibrates by vibration of the first drive section and is displaced in response to the angular velocity, and a first fixed electrode fixed to the substrate and facing the first movable electrode. The second detection section includes a second movable body including a second movable electrode that vibrates by vibration of the first drive section and is displaced in response to the angular velocity, and a second fixed electrode fixed to the substrate and facing the second movable electrode. The first movable body and the second movable body are coupled together by a first coupling section.
