Abstract
A sensor includes a plurality of weight portions which swivel, support parts each of which supports at one end a corresponding one of the plurality of weight portions in the same direction, and a driving part which supplies driving power to the support parts to swivel the plurality of weight portions. The driving part swivels at least one weight portion of the plurality of weight portions in a first direction and a remaining weight portion in a second direction opposite to the first direction so that the angular velocity about an axis parallel to a predetermined swivel locus of the at least one weight portion, excluding an acceleration component in the direction of the axis, can be detected from the difference between a deviation of a swivel locus of the at least one weight portion from the predetermined swivel locus and a deviation of a swivel locus of the remaining weight portion from a predetermined swivel locus thereof.
