Abstract
A vibrating gyroscope comprising includes a vibrating body. At least one driving member is located on the vibrating body and vibrates the vibrating body in a vibrating direction that is substantially perpendicular to an axis of said vibrating body. At least two detection members are located so as to be spaced from each other on the vibrating body and located on opposite sides of a plane including the axis and the vibrating direction of the vibrating body. The at least one driving member is arranged in a non-parallel relationship relative to each of the at least two detection members. The at least two detection members are arranged to detect a rotational angular velocity applied to the vibrating body and the at least two detection members are arranged in a non-parallel relationship relative to each other.
