A gyro sensor includes a substrate, a fixed section fixed to the substrate, a driving section configured to perform driving along an X axis parallel to a principal plane of the substrate, a mass section coupled to the driving section and displaced along the X axis, a detecting section coupled to the mass section, capable of turning around a Z axis crossing the X axis, and capable of being displaced along the Z axis by a Coriolis force acting on a turning motion horizontal to the substrate, and an elastic section coupling the detecting section and the fixed section. The fixed section is disposed between the center of gravity of the detecting section and the mass section in a plan view.
