PROBLEM TO BE SOLVED: To provide a piezoelectric transformer for increasing reliability, for achieving miniaturization, weight reduction and high efficiency, and for realizing the increase of an output voltage. SOLUTION: In this piezoelectric transformer, a piezoelectric body 1 is provided with a vibrator 6 formed with electrodes 2 and 3 for input and an electrode 4 for output, and the vibrator 6 is excited by applying an AC signal to the electrodes 2 and 3 for input so that an output signal can be outputted from the electrode 4 for output. The piezoelectric body 1 is formed like a sheet by high polymer piezoelectric materials, and provided with a support 5 for supporting one or more piezoelectric bodies and for increasing apparent mechanical quality coefficients.
