<P>PROBLEM TO BE SOLVED: To provide an inexpensive piezoelectric device has a good conductivity between a wiring pattern on a substrate and an exciting electrode on the surface of a piezoelectric element, and also a method of manufacturing the piezoelectric device. Ž<P>SOLUTION: The piezoelectric element 2 is directly mounted on a wiring pattern 11 provided on a substrate 1 without any conductive member such as a conductive adhesive provided between the wiring pattern 11 and an exciting electrode 2a on the surface of the piezoelectric element 2. The wiring pattern 11 on the substrate 1 is mechanically and electrically connected to the exciting electrode 2a on the piezoelectric element 2 by a means for enabling direct junction, e.g., by welding. With such an arrangement, since a conductive member, which has been provided between the wiring pattern 11 and the exciting electrode 2a, is eliminated, its material cost is correspondingly reduced and a conductivity between both is increased.
