Abstract
A vibrator has a construction that allows its electrodes to be easily formed and requires a smaller number of the assembly man-hours. The vibrator includes a drive electrode and two detection electrodes that are disposed along a length direction thereof, on a planar portion provided on the surface of a vibrating member defined by piezoelectric body. These electrodes constitute interdigital electrode portions defined by mutually opposed comb electrodes which are arranged such that the direction in which the teeth thereof extend is substantially perpendicular to the length direction of the vibrating member.
