Angular velocity and acceleration sensor

An external-force detecting sensor (1) includes a sensor unit (2) for commonly detecting angular velocity and acceleration; an angular-velocity/acceleration mix signal outputting unit (24) for outputting an angular-velocity/acceleration mix signal comprised of an angular-velocity component in accordance with the magnitude of angular velocity and an acceleration component in accordance with the magnitude of acceleration that are detected by the sensor unit; and a signal separating unit (27,30) for separating and extracting the angular-velocity component and the acceleration component from the angular velocity/acceleration mix signal to output as an angular-velocity signal and an acceleration signal.
