摘要: Provided herein is a vibration-type angular velocity sensor capable of improving detection precision of angular velocities around the Z axis and preventing detection precision of angular velocities around the X and Y axes from deteriorating. 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.

摘要: A semiconductor sensor of the present invention is capable of preventing a diaphragm portion of the sensor from being damaged if a weight collides against a semiconductor integrated circuit substrate of the sensor and is further capable of preventing the diaphragm portion from being bent significantly even when a semiconductor sensor element of the sensor is disposed inside a distorted or deformed casing. A rear surface of the semiconductor integrated circuit substrate 7 is joined onto a wall surface of the casing 9 that defines a receiving chamber of the casing. A support portion of the semiconductor sensor element is joined onto a front surface 7a of the semiconductor integrated circuit substrate 7. A shock absorbing layer is formed on the front surface 7a of the semiconductor integrated circuit substrate 7 at least on a part thereof facing the weight 3 of the semiconductor sensor element 7, for suppressing the bouncing of the weight 3 when the weight 3 collides against the semiconductor integrated circuit substrate 7.
