Abstract
A weight of an inertial sensor if formed from a plurality of divided weights, and the divided weights are connected to each other by elastically deformable beams. A movable range and a mass of each of the divided weights and a rigidity of each of the beams are adjusted and a plurality of deformation modes having different sensitivity ranges with respect to the acceleration are used in combination. By this means, it is possible to improve a detecting sensitivity of an acceleration and widen an acceleration response range.
