A weight 3 is columnar or conic. The outline of an outer peripheral portion of a diaphragm 1 has such shape that a straight portion ST is formed at each of four corner portions of a square. Four vibration exciting electrodes 11 are respectively located in four regions partitioned by a first imaginary line L1 and a second imaginary line L2. Four angular velocity sensing electrodes 13 are respectively located in four regions partitioned by a first imaginary diagonal line CL1 and a second imaginary diagonal line Cl2.
