In a structure in which a piezoelectric transformer element ( ) is mounted on a circuit board ( ) equipped with a circuit component for driving the piezoelectric transformer element ( ), at least one of a fixing member ( ) and a supporting member ( ) made of an elastic material having flexibility is interposed between the piezoelectric transformer element ( ) and the circuit board ( ) so as to cover vibration node portions ( ) of the piezoelectric transformer element ( ) and at least a part of the remaining portion except the vibration node portions ( ). Thus, the piezoelectric transformer element ( ) is fixed to the circuit board ( ).
