PROBLEM TO BE SOLVED: To provide a piezoelectric pronunciation device, in which a first terminal member and a second terminal member are formed inexpensively without using plating and the like. SOLUTION: A piezoelectric element 5 and a second piezoelectric element are connected to both sides of a diaphragm 3 to constitute a piezoelectric oscillating body 1. A perimeter portion of the diaphragm 3 and a circular frame portion of a ring-shaped main body, which constitutes a support body 11 around the diaphragm 3 are jointed with a linking means 19 made up of synthetic resin insulation sheet 21. A first metal terminal member 13 and a second metal terminal member 15 are supported by a terminal holding unit 19a of the ring-shaped main body 17. With a first drawing conductor unit 23 of a first drawing means 25, a first electrode 5a of the first piezoelectric element 5 and the first terminal member 13 are connected electrically. With a second drawing conductive unit 29 of a second drawing means 31, a first electrode 7a of the second piezoelectric element 7 and the first terminal member 13 are connected electrically. With a connecting conductor unit 35 of a connecting means 37, the perimeter portion of the diaphragm 3 and the second terminal member 15 are connected electrically. COPYRIGHT: (C)2008,JPO&INPIT
