Abstract
An angular rate sensor includes: a substrate; and a vibrator having a beam part supported in a state of floating from the substrate and a pair of supports formed on the substrate and provided at both ends of the beam part for supporting the beam part. The vibrator includes a piezoelectric film formed in the beam part, a detecting electrode for detecting an angular rate, the detecting electrode being formed on the piezoelectric film so as to extend toward a center portion of the beam part from one end thereof, and a driving electrode for vibrating the vibrator, the driving electrode being formed on the piezoelectric film so as to extend toward the center portion of the beam part from the other end thereof and to be spaced from the detecting electrode.
