Abstract

PURPOSE:To secure the high-performance and sudden selection property by providing a pair of electrodes on the surface of a pair of rectangular parallelepiped piezoelectric ceramic plates along with the earth electrode and the lead-out electrode provided on the back of the ceramic plate and to a pair of electrodes on the surface of the ceramic plate respectively. CONSTITUTION:A pair of electrodes 6a and 7a plus 6b and 7b are provided on the surfaces of rectangular parallelepiped piezoelectric ceramic plates 5a and 5b, and earth side electrodes 8a and 8b opposing to each other and covering over a pair of electrodes 6a and 7a are provided on the back surfaces of plate 5a and 5b. In addition, lead-out electrodes 9a, 10a, 11a plus 9b, 10b, 11b are provided to a pair of electrodes 6a, 7a, 8a and others on the surfaces of plates 5a and 5b. And then two elements are placed on insulated substrate 12, and the connection is given between electrodes via the solder or the like. As a result, the high-performance and sudden selection property can be obtained.
