Abstract
A small-sized, high detection sensitivity and high performance acceleration sensor having directional or non-directional sensitivity is disclosed. The acceleration sensor is provided with a vibrator having uni-directional polarization and a weight connected to the vibrator. The weight is supported at the position different from the center of gravity of the total body of the vibrator and the weight itself. The vibrator is disposed so that its direction of polarization axis is either consistent or inconsistent with an axis of the torsion of the vibrator.
