Abstract
A vibrating element includes a vibrating arm for detection. An electrode is provided on the vibrating arm for detection. A wiring line is connected to the electrode. The wiring line is arranged on a piezoelectric body of a base portion. At least a part of the wiring line is an electrode for adjustment. The electrode for adjustment generates an electrical signal with an opposite phase to an output signal of leak vibration of the vibrating arm for detection.
