摘要：
This vibrating element includes a movable portion driven to vibrate at a prescribed resonance frequency, a driving portion vibrating the movable portion by cyclically supplying a pulse signal and a detecting portion detecting the vibrational state of the movable portion, while the driving portion is so formed as to supply the pulse signal at a first frequency substantially identical to the resonance frequency of the movable portion at least in starting and to cyclically supply the pulse signal at a second frequency smaller than the first frequency in detection of the vibrational state of the movable portion.
