The present invention aims to provide an angular velocity detection device which is capable of reducing the effect of coupling between a drive electrode and a first displacement detection electrode by a floating capacity, and is low in cost. In the angular...

An external-force detecting apparatus (301) includes one or more drive lines (LD) connecting the corresponding drive electrodes to a driving unit (251) and one or more monitor lines LM connecting the corresponding monitor electrodes to the driving unit (25...
