Abstract
A downsized angular velocity sensor is disclosed in which the detection sensitivity is improved. An oscillator oscillatably supported by support beams along two horizontal axes is formed of two rod-like members extending along the Y axis and an interconnecting portion. A hollow region is formed between each of the rod-like members and the interconnecting portion. Displacement detecting sections are disposed in the hollow regions. The displacement detecting sections are each constructed of an antenna-like electrode array, so that a greater amount of change in capacitance generated between the antenna-like electrodes can be obtained.
