Abstract
An angular velocity sensor has a weight portion that can be drive-oscillated in a driving direction and be oscillated in a detecting direction when an angular velocity is applied, and unnecessary oscillation suppressing electrodes that can generate an electrostatic force to be applied to the weight portion in the detecting direction. The electrostatic force prevents the weight portion from being drive-oscillated in a direction other than the driving direction. As a result, unnecessary oscillation of the weight portion can be prevented even when the angular velocity sensor has a processing error.
