Claim Text:
1. A gyro sensor comprising: a vibrating body that performs drive-vibration along a driving vibration direction, the vibrating body having first through fourth sides; first and second fixed drive electrodes that are disposed at the first side of the vibrating body so as to be spaced apart from the first side in a plan view; third and fourth fixed drive electrodes that are disposed at the second side opposite to the first side of the vibrating body so as to be spaced apart from the second side in the plan view; first and second detection electrodes that detect a signal changing according to angular velocity of the vibrating body; first and second drive wirings that are connected to the first and second fixed drive electrodes, respectively, the first and second drive wirings being disposed at the first side and the third side of the vibrating body so as to be spaced apart from the first and third sides; third and fourth drive wirings that are connected to the third and fourth fixed drive electrodes, respectively, the third and fourth drive wirings being disposed at the second side and the third side of the vibrating body so as to be spaced apart from the second and third sides; and first and second detection wirings that are connected to the first and second detection electrodes, respectively, the first and second detection wirings being disposed at the fourth side opposite to the third side of the vibrating body so as to extend from the fourth side.
