ABSTRACT:
A vibrator for generating a signal for measuring a physical quantity using a vibrator is provided, including at least one bending vibration arm vibrating in bending mode along a specified plane and having a first end, an opposed second end, and first and second main faces that are substantially parallel with each other. A base portion is provided at the first provided at the first end of the bending vibration arm, a weight portion is provided at the second end of the bending vibration arm, and grooves are formed on the first and second main faces. The vibrator further includes driving means for exciting a driving vibration in the vibrator, and detecting means provided on one of the bending vibration arms for detecting an output signal based on detection vibrations induced in the vibrator responsive to the physical quantity to be measured.
