PROBLEM TO BE SOLVED: To provide a piezoelectric transformer which can be shorter, together with its mounting method which supports a piezoelectric transformer well without causing lowering in characteristics, while giving stable vibration. SOLUTION: A pedestal bracket 22 is soldered in advance to a wiring pattern 34 of a mounting substrate 30. A conductive bond 42 is applied to the pedestal bracket 22, while a rubber bond is applied to the position of a secondary node point PN2 on the mounting substrate 30. A piezoelectric transformer 10 is bonded almost in parallel on the mounting substrate 30 so that the position of pedestal bracket 22 and application point of the rubber bond become the node points PN1 and PN2, respectively. A presser bracket 20 is bonded with a conductive bond 46 so as to be on the primary node point PN1 of the piezoelectric transformer 10, while a leg part 20A of the presser bracket 20 is soldered to a wiring pattern 32 of the mounting substrate 30. Then a secondary lead-out line 24 is soldered to a wiring pattern 36 of the mounting substrate 30.
