Abstract
A laminated piezoelectric transducer, comprising a laminate of a plurality of piezoelectric plates with paste electrodes inserted therebetween and bonding the plates together. Rows of metal extrusions are made by electroless plating onto the paste electrodes on the peripheral outer surface of the laminate. Each row of the metal extrusions is formed onto and electrically connected to alternate paste electrodes, so that by electrically connecting each row of the metal extrusions, the laminate of the piezoelectric plates is electrically connected in parallel. This laminated piezoelectric transducer allows the formation of the paste electrodes on the entire or at least substantially the entire main surfaces of the piezoelectric plates, and eliminates the need for the usual metal plate electrodes inserted between the piezoelectric plates.
