Abstract
An acceleration sensor includes a substrate, first and second torsion beams, first and second detection frames, first and second detection electrodes, first and second link beams, and an inertial mass body. The first and second torsion beams are distorted around the first and second torsion axes. The first and second detection frames are rotated about the first and second torsion axes. The first and second detection electrodes detect an angle formed between the substrate and each of the first and second detection frames. The first link beam is on a first axis located at a position shifted from a position of the first torsion axis to one end side of the first detection frame along a direction crossing the first torsion axis. The second link beam is on a second axis located at a position shifted from a position of the second torsion axis in a direction identical to the direction of shift from the position of the first torsion axis.
