Claim Text:
1. A vibrating element comprising: a drive vibrating portion configured to perform a drive mode; and a detection vibrating portion configured to perform first and second detection modes in which the detection vibrating portion vibrates in a direction orthogonal to a vibration direction of the drive vibrating portion in the drive mode, wherein when a resonance frequency in the drive mode is fa, a resonance frequency in the first detection mode is fb, and a resonance frequency in the second detection mode is fc, the fa falls between the fb and the fc, and in first through third frequency-temperature characteristic curves representing the drive, first detection and second detection modes, respectively, when a turnover temperature of the first frequency-temperature characteristic curve of the fa is Ta [° C.], a turnover temperature of the second frequency-temperature characteristic curve of the fb is Tb [° C.], and a turnover temperature of the third frequency-temperature characteristic curve of the fc is Tc [° C.], the Ta is lower than the Tb and the Tc, or the Ta is higher than the Tb and the Tc.
