Technical Examples
  1. A receiver of an ultrasonic sensor includes reception elements, each of which has a shape of a flat rectangular plate. The reception elements are arranged one-dimensionally on a plane so that the reception surfaces face the same direction and that the reception elements are aligned with small intervals in the width direction thereof while longitudinal ends of the reception elements at a certain side are aligned in a straight line. The widths and the thicknesses of the reception elements are even, while the longitudes of the reception elements are uneven. The both longitudinal ends of the reception elements are fixed to prohibit the vibration of the ends. The longitudes are designed so that the primary resonance frequencies of the reception elements are uneven.
