ABSTRACT:
Each of excitation elements and receiving elements placed in a frame region of a non-piezoelectric substrate is constructed by forming a comb-like electrode on the front face of a piezoelectric body and forming a plate electrode (solid electrode) on the rear face thereof. The comb-like electrode is composed of a bus electrode and a plurality of V-shaped electrode fingers extended from the bus electrode. Drawn-round wires are provided to connect the comb-like electrode (bus electrode) and plate electrode to external circuits. Surface acoustic waves from the excitation elements located on the upper side and the lower side are simultaneously propagated in two directions respectively and the propagated surface acoustic waves are received by receiving elements located on the left side and the right side respectively.
