Abstract

A gyro vibrating element includes a drive signal pattern including a drive signal electrode to which a drive signal is applied and a drive signal wire connected to the drive signal electrode, a first detection signal pattern including a first detection electrode that outputs a first detection signal and a first detection signal wire connected to the first detection electrode, the first detection signal pattern being capacitively coupled to the drive signal pattern, and a second detection signal pattern including a second detection electrode that outputs a second detection signal opposite in phase to the first detection signal and a second detection signal wire connected to the second detection electrode, the second detection signal pattern being capacitively coupled to the drive signal pattern. Any one of the first detection signal pattern, the second detection signal pattern, and the drive signal pattern includes an adjustment pattern for adjusting an area of the signal pattern.
