To provide an angular-velocity measuring apparatus by which an angular velocity is detected with high accuracy over a long period even when the crosstalk of a driving signal is generated.

An angular velocity sensor 11 is attached to a substrate 12, and interconnections 13, 14 for drive and interconnections 15, 16 for detection which are situated around the sensor 11 and to which the driving signal is input are arranged and installed at the substrate 12. First electrodes 17, 18 for adjustment which are extended along the interconnection 15 for detection are installed at the interconnections 13, 14 for drive, and second electrodes 19, 20 for adjustment which are extended along the interconnection 16 for detection are installed. When the electrodes 17 to 20 for adjustment are cut and removed partially, capacitances C1' to C4' across the interconnections 13, 14 for drive and the interconnections 15, 16 for detection can be reduced individually, and the crosstalk of the driving signal with reference to the interconnections 15, 16 for detection can be made nearly equal.
