Claim Text:
1. A sensor element comprising: a base part; a first arm extended from the base part and capable of drive-vibrating; a second arm extended from the base part, the second arm vibrating as a result of the drive-vibrating of the first arm; a first electrode provided on the second arm and the first electrode capable of generating a first signal with the vibration of the second arm; a second electrode provided on the second arm and the second electrode capable of generating a second signal having an opposite phase to the first signal with the vibration of the second arm; and a detection part containing a detection electrode configured to output a third signal in response to a physical quantity applied to the first arm, wherein the first electrode and second electrode are electrically connected to the detection electrode such that a sum of the first signal and the second signal are superposed on the third signal, and wherein the sum of the first signal and the second signal has an opposite phase to the third signal generated from the detection electrode when no physical quantity is applied to the first arm.
