ABSTRACT:
A piezoelectric filter comprises a piezoelectric substrate having separate first and second electrode layers formed on one surface thereof and a common electrode layer formed on the opposite surface thereof, first and second terminal members, and a common terminal member electrically connected to the common electrode layer. The first and second terminal members are electrically connected to the first and second electrode layers through different local areas of a direction-oriented electroconductive plastic sheet capable of exhibiting its electroconductivity in a predetermined direction across the thickness thereof. An ordinary electroconductive rubber sheet may be positioned between the common terminal member and the common electrode layer.
